Abstract:
Piezoelectric actuators find extensive application in delivering precision motion in the micrometer to nanometer range. The advantages of a broader range of motion, rapid response, higher stiffness, and large actuation force from piezoelectric actuators make them suitable for precision positioning applications. However, the inherent nonlinearity in the piezoelectric actuators under dynamic working conditions severely affects the accuracy of the generated motion. The nonlinearity in the piezoelectric actuators arises from hysteresis, creep, and vibration, which affect the performance of the piezoelectric actuator. Thus, there is a need for appropriate modeling and control approaches for piezoelectric actuators, which can model the nonlinearity phenomenon and provide adequate compensation to achieve higher motion accuracy. The present review covers different methods adopted for overcoming the nonlinearity issues in piezoelectric actuators. This review highlights the charge-based and voltage-based control methods that drive the piezoelectric actuators. The survey also includes different modeling approaches for the creep and hysteresis phenomenon of the piezoelectric actuators. In addition, the present review also highlights different control strategies and their applications in various types of piezoelectric actuators. An attempt is also made to compare the piezoelectric actuator’s different modeling and control approaches and highlight prospects.

Abstract:
Piezoelectric actuators are the most commonly used actuators in nanopositioning. They provide excellent operating bandwidth and precision. These actuators are normally driven by voltage amplifiers; however, the relationship of the applied voltage on the actuator and its position is nonlinear and complex due to phenomena such as hysteresis. This adversely influences actuator’s position control which is the core component of nanopositioning. However, the electrical charge applied on a piezoelectric actuator has a significantly less complex relationship with its position. As a result, driving piezoelectric actuators with charge amplifiers has attracted significant attention. In this article, charge driving methods are classified, and their advantages, major issues and the solutions to these issues are critically reviewed.

Abstract:
Piezoelectric actuators are characterized by high positioning accuracy, high stiffness and a fast response and are widely used in ultra-precision machining technologies such as fast tool servo technology and ultrasonic machining. The rapid response characteristics of piezoelectric actuators often determine the overall quality of machining. However, there has been little research on the fast response characteristics of piezoelectric actuators, and this knowledge gap will lead to low precision and poor quality of the final machining. The fast response characteristics of a piezoelectric actuator were studied in this work. Firstly, the piezoelectric actuator was divided into a no-load state and a load state according to the working state. A fast response analysis and output characteristic analysis were carried out, the corresponding dynamic model was established, and then the model was simulated. Finally, an experimental system was established to verify the dynamic model of the piezoelectric actuator’s fast response by conducting an experiment in which the piezoelectric actuator bounces a steel ball. The experimental results verify the correctness of the model and show that the greater the cross-sectional area and height of the piezoelectric actuator, the higher the bouncing height of the ball, and the better the dynamic performance of the piezoelectric actuator. It is believed that this study has guiding significance for the application of the dynamic characteristics of piezoelectric actuators in the machining field.

Abstract:
This paper experimentally investigates the performance of piezoelectric force actuators. Using the same encapsulated piezoelectric stack, an inertial-type actuator and a frame-type actuator are constructed for performance comparison. The experimental results are also used to validate the recently established actuator models, whilst the mechanical and piezoelectrical parameters of the models are experimentally identified. The performance of the actuators is described by the transmitted force(s) and input power flow from the actuators to the base structure with reference to the same electrical input voltage to the stack. The validation is deemed successful due to the strong agreement observed between the measured and predicted actuator performances. Additionally, it is discovered that the frame-type actuator has the capacity to produce significantly higher transmitted forces and input power flow to the base structure compared to the inertial-type actuator. The mechanism underlying the performance disparity between these two types of actuators is also examined. This paper clarifies the mechanism, shedding light on the design and optimization of piezoelectric actuators.

Abstract:
Piezoelectric actuators usually operate under a high frequency driving signal. Here we report a harmonic rotating piezoelectric actuator by coupling a harmonic wave generator and a friction rotor, in which the actuator can be actuated by a low-frequency sinusoidal signal with positive bias. The harmonic wave is generated by a two-stage magnifying mechanism consisting of a displacement amplifier and a harmonic rod. Applying piezoelectricity theory, the actuator’s output characteristic equations are deduced. What is more, the output characteristics of piezoelectric actuators are tested with the established experimental system. Results show that the generated harmonic displacements can drive the actuator to work normally at a driving voltage of larger than 90 V and the maximum total harmonic displacement of the piezoelectric actuator comes up to 427.6 μm under the driving voltage of 150 V. Meanwhile, the error between the measured and calculated values of the harmonic displacement is less than 7%. Furthermore, the rotational speed of the piezoelectric actuator reaches 5.45 rpm/min at 150 V voltage and 5 Hz driving frequency.

Abstract:
This paper presents a novel piezoelectric actuator containing double pushers. By using finite element analysis software, this study simulated the vibration mode and amplitude of piezoelectric actuators. The Taguchi method was used to design the parameters of piezoelectric actuators including length, width, height, and electrodes setting. This paper also presents a discussion regarding the influence that the design parameters had on the actuator amplitudes. Based on optimal design parameters, a novel piezoelectric actuator containing double pushers is produced and some thrust tests are also carried out. From the experiment results, the piezoelectric actuator containing double pushers can provide a greater thrust force than that of traditional actuators containing a single pusher as the preload is greater. Comparing with the traditional actuators, the thrust force of new actuator can be increased by 48% with the double preload.

Abstract:
Piezoelectric actuators are widely used as fine-motion actuators for positioning devices. Current pulse driving reduces displacement hysteresis, and the drive circuit provides current pulses considered constant charge pulses to the piezoelectric actuator. The circuit for devices with multiple degrees of freedom using multiple piezoelectric actuators should be simple. Matrix circuits are used to drive liquid crystal displays to reduce the number of drive-circuit control signals and components. A group of 2 × 2 piezoelectric actuators was driven alternately using a 4-switch matrix circuit, and two field effect transistors were used as a fast matrix circuit switch. Piezoelectric actuator drive performance was studied in the case of using the current pulse circuit and the matrix circuit. When the matrix circuit drove actuators performing as capacitive loads, switching device junction capacitors adversely affected drive performance.

Abstract:
Piezoelectric ceramics are a very popular material in the field of actuator technology due to their unique piezoelectric properties. However, the brittle behavior of ceramics endangers the reliability of piezoelectric actuators. In this article, the three-dimensional braided piezoelectric composite is utilized to ameliorate the reliability and driving capability of piezoelectric actuators. The static analysis of laminated beam with the distributed braided piezoelectric composite actuator is presented to study its driving capability. Based on the piezoelectric constitutive equations and Euler–Bernoulli beam theory, the governing equation of the piezoelectric laminated beam is derived. The least-squares method for the piezoelectric laminated beam is established to solve the derived governing equation. The current approach is validated by comparison with published results and finite element results. In the numerical examples, the effects of the number and spacing of the three-dimensional braided piezoelectric composite patches, actuator central location, actuator length, actuator thickness ratio, cantilever beam thickness, applied voltage and fiber volume fraction on the driving capability of the distributed braided piezoelectric composite actuator are investigated. This study suggests the potential use of the distributed braided piezoelectric composite actuator in intelligent structures and provides useful guidance for the design and optimization of piezoelectric actuators.

Abstract:
In the present work, investigation of the functional property of piezoelectric graded monomorph actuator systems is presented. The functional graded actuators were fabricated by electrophoretic deposition (EPD) using pure PZT and doped PZT materials. Actuators developed have shown gradual gradient variation in microstructure. It is noted that trend in microstructural gradient does not represent similar trend in piezoelectric property gradient. The displacement of microstructural graded and both piezoelectric and microstructural graded actuators were measured. The results show that the gradient distribution of the piezoelectric properties is important to improve the electromechanical performance of the actuator.

Abstract:
This paper presents a novel approach for improving the reliability and driving capability of piezoelectric actuators by developing braided fiber piezoelectric composite (BFPC) actuators. The nonlinear analysis of laminated beams integrated with the BFPC actuators under electric load is presented. According to Timoshenko beam theory and von Kármán nonlinear geometric relation, the strain components of the piezoelectric laminated beams are obtained. The nonlinear governing equations of the piezoelectric laminated beams are derived by the Galerkin method and principle of minimum potential energy, and then are solved through the direct iterative method. The accuracy of this method is demonstrated by its comparison with the published results. The driving capability of the BFPC actuator and the existing piezoelectric composite actuator is compared. The influences of the fiber volume fraction, actuator thickness, simply supported beam thickness and applied voltage on the driving capability of the BFPC actuators are discussed through a comprehensive parametric study. The numerical results illustrate that the BFPC actuators with excellent driving capability can effectively control the deformation of smart structures.

Abstract:
Planar-spiral piezoelectric-unimorph-actuators, that deflect out-of-their-plane, were modelled, designed and fabricated. A range of other planar piezoelectric-device designs has also been made. These include spokes, multi-arms, plates and swastikas. All these devices consisted of a mechanical support in the plane with a piezoelectric layer deposited on top. Impedance spectra demonstrated that a fabricated device was piezoelectrically active. Finite-element (FE) models of straight and spiral piezoelectric- unimorph-actuators were constructed. The mechanical stiffness of the spiral-beam was increased with the curvature of the beam; consequently, the inner coils exhibited virtually no deflection and appeared to be redundant. The advantage of the spiral-actuators is that they allow large actuator lengths to be contained compactly without the loss of mechanical stiffness. Fabrication of the above devices necessitated the development of new fabrication technologies. The active-piezoelectric and mechanical-support were a lead zirconate titanate (Pb(Tii_XZrx)O3 - PZT) thick-film and a-platinised-silicon-wafer respectively. Vias were opened in the PZT with wet etching, and this was completed without damaging the back electrode. Powder blasting allowed any 2-dimensional-shape to be cut into the device wafer. Devices were released from the Si support with deep-reactive-ion-etching (DRIE). The PZT thick films were fired with a Cu20-PbO eutectic additive. Pb and Cu were considered to dope on A and B lattice sites (of PZT) respectively, when the PZT was sintered at high oxygen-partial-pressure (p02). The electrical conductivity of PZT thick films was increased when they were sintered at low P02, and this was moderated by the presence of Cu' as an acceptor ion. A lead-platinum intermetallic and lead silicate glass phase simultaneously formed under sintering conditions of low pot, and this simultaneous formation, was accounted for by a six-stage mechanism. Step 1, residual C in the thick film reduces PbO to Pb followed by step 2 where Pb diffuses into the Pt back electrode. In step 3, Pt3Pb formation occurs in the intermetallic layer followed by step 4 in which PtPb forms. Step 5 occurs with saturation of the intermetallic layer as Pb continues to diffuse from the thick film. There is additional diffusion of Pb into the underlying Si substrate. Finally step 6 occurs at some later point, when P02 has risen, Pb is oxidised to PbO, and Si is oxidised to Si02. PbO and Si02 can flux to form PbSiO3 The glass was found to undermine film/substrate adhesion.

Abstract:
Since the first models developed in the late 19th century, the applications of piezoelectric materials have been progressively growing in number. The capacity of these materials to couple electric and mechanic fields makes them perfect candidates in the study of geometrical morphing. Their application in aeronautical products has been traditionally seen from two different perspectives: their use as sensors and as actuators. Both functions present potential benefits and improvements with promising applications. While the investigations in the past years focused mainly in the analysis and integration of piezoelectric materials in structures as means of implementing what is known as structural health monitoring systems, the application of this type of materials as actuators in the geometrical control of structures also awakes interest in the scientific community. In its present state of development, the technology for morphing of structures using piezoelectric actuators is not yet advanced enough as to integrate such systems in commercial products. However, the field is in continuous development and the evolution of the materials and the integration solutions bring the technology closer to industrial application. This thesis aims at studying the feasibility of application of piezoelectric-actuated morphing aeronautical structures in current aircraft concepts. The analysis is performed at theoretical and experimental levels analyzing the static and dynamic performance of currently available actuators and motion amplification technologies. The research presented in this thesis is directed in two different applications of utilization of the actuators: as static actuators producing deformation of the aerodynamic surface and as dynamic actuators controlling a classic aerodynamic control surface. In each of the applications a different type of piezoelectric actuator architecture has been used: a piezoelectric patch has been selected for static morphing applications and a piezoelectric stack-based actuation system for the dynamic control of the conventional control surface. The static experiments performed aimed at demonstrating the suitability of piezoelectric actuators as morphing devices. This analysis was performed analyzing the deflections produced in the trailing edge of an aerodynamic profile. The analysis of the obtained experimental results showed promising results as the actuating configurations managed to perform as designed. The static experiments showed substantial deformation of the trailing edge of the wing profile making this configuration mature enough for further experimentation such as wind tunnel testing. The deflections produced were, however, not significant enough for the direct application of the solution into larger scale configurations. Scalability of the technological solutions remains one of the major challenges of the technology in the morphing applications. The dynamic results showed good performance of the actuators in an anti-flutter demonstrator application during wind tunnel testing. The experiments showed that the system remained stable well passed the flutter velocity; this allows for further experimentation in structures presenting higher flutter speeds. With the development of the next generation of advanced piezoelectric ceramics, with piezoelectric coefficients twice as large in comparison to PZT-based ceramics, the application of the deforming structure concept is very promising for application in larger demonstrators in both static and dynamic applications. The next generation of piezoelectric materials presents itself as a first step into a solution to the scalability of the technology for application into full-scale demonstrators.
Des dels primers models desenvolupats durant el segle XIX, les aplicacions per a materials piezoelèctrics han anat creixent progressivament. La relació que presenten aquests materials entre el comportament mecànic i el comportament elèctric els converteix en candidats ideals en l'estudi d'estructures deformables. L'aplicació de piezoelèctrics en aeronàutica es concep tradicionalment des de dues perspectives: com a sensors o com a actuadors. Ambdues presenten potencials beneficis i aplicacions. Tot i que en els últims anys la recerca s'ha concentrat en l'estudi d'integració dels materials en sistemes que permeten controlar la salut de l'estructura (Structural Health Monitoring), l'aplicació de piezoelèctrics com a actuadors d'estructures deformables desperta l'interès de la comunitat científica. En l'estadi actual, la tecnologia necessària per deformar estructures de forma controlada utilitzant materials piezoelèctrics no està suficientment desenvolupada. No obstant, la recerca en aquest camp està en continu desenvolupament i s'apropa a solucions que permetran integrar-la en aplicacions industrials. L'objectiu de la tesi és estudiar la possibilitat d'utilitzar deformacions produïdes mitjançant actuadors piezoelèctrics en estructures aeronàutiques actuals. L'anàlisi està orientat des de punts de vista teòric i experimental i es centra en el comportament estàtic i dinàmic de solucions tecnològiques amb actuadors i tecnologies d'amplificació disponibles comercialment. La recerca que es presenta en la tesi estudia dues aplicacions diferents en l'ús d'aquest tipus d'actuadors: com a actuadors en regim estàtic, produint deformacions de la superfície aerodinàmica, i com a actuadors dinàmics, que controlin una superfície de control convencional. L'arquitectura de la solució tecnològica emprada ha estat diferent en cada aplicació: en la deformació estàtica de la superfície aerodinàmica l'actuador és de tipus "patch" mentre que en el cas dinàmic és de tipus "stack". Els experiments estàtics desenvolupats tenen com a objectiu demostrar la capacitat dels piezoelèctrics com a elements que produeixin deformacions en l'estructura (morphing). Aquest objectiu es demostra analitzant les deflexions produïdes en el caire de fuga d'un perfil aerodinàmic. Els resultats experimentals obtinguts són optimistes ja que les diferents configuracions d'actuadors es comporten tal i com prediuen els models. En règim estàtic, les deformacions produïdes en el caire de fuga son substancials. Això permet assegurar que la configuració utilitzada en els experiments és prou madura com per seguir investigant, per exemple, en túnel de vent. Malgrat això, les deformacions produïdes encara no són suficientment significatives com per integrar l'experiment en un model més gran. L'escalabilitat és un dels reptes més importants que presenta la tecnologia en aplicacions de "morphing". Els resultats dinàmics demostren una bona actuació de l'actuador integrat en un sistema anti-flameig en els experiments en túnel de vent. Els experiments demostren la capacitat del sistema de mantenir-se estable a velocitats mes enllà de l'aparició del flameig. El següent pas en aquesta línia de recerca es l'investigació en models més complexos en quant a aparició de flameig. Amb el desenvolupament d'una nova generació de materials piezoelèctrics ceràmics avançats, que promet coeficients piezoelectrics el doble d'alts en comparació amb els materials basats en PZT disponibles actualment, l'arquitectura experimentada en règim estàtic és un molt bon candidat en aplicacions a escala més gran. Aquesta propera generació de materials es presenta com un primer pas en solucionar els problemes d'escalabilitat que presenta la tecnologia actualment.

Abstract:

This thesis describes work on piezoelectric shear modeactuators used in dropon- demand ink printing applications.These actuators comprise an array of ink channels micromachinedinto bulk Pb(ZrxTi1-x)O3(PZT) ceramics.

During this study, a new pulsed spectroscopic technique wasdeveloped to investigate functional properties of a singlechannel wall of the actuator. The pulse technique is based onrecording the transient current in response to a short voltagepulse applied to the channel wall. An electric field appliedperpendicular to the polarization will cause a shear motion ofthe wall. If a voltage pulse with a fast rise time is highenough in amplitude to actuate the wall, it will act like atuning fork and oscillate at it’s resonant frequencies.Because of the piezoelectric effect, the mechanicaloscillations of the wall can be seen as oscillations in thetransient current.

Beside the pulsed technique, dielectric spectroscopy,ferroelectric hysteresis loop tracing and stroboscopy were usedas characterization techniques. The results obtained arediscussed in respect to temperature dependence, frequencydispersion, ferroelectric fatigue and acoustic resonancemodes.

Another field of interest was the temperature inside theactuator. An electric circuit, based on the voltage dividerprinciple, was built to monitor the ink temperature as afunction of the printing pattern.‘Dummy walls’,located at the beginning and the end of the channel wall array,were used as temperature sensing elements. Since the dielectricpermittivity of the PZT channel walls depends on temperature,the capacitance of the‘dummy walls’changes withtemperature. The information obtained by this measurementtechnique was used to investigate alternative materials for thepassive components of the actuator.

A further part was the development of a new actuator designcalled a‘Chevron actuator’. Chevron actuatorsinclude an additional PZT layer with polarization in theopposite direction to the base plate polarization. Thus, thewhole channel wall is used as the active part instead of usingjust the upper half as in the standard actuator. The mainadvantage of this technique is a reduced power consumption ofthe actuator and therefore less heat dissipation.

Different approaches were used to construct Chevronactuators. Experiments determined the efficiency of theactuators and these results were used to make improvements. TheChevron actuators were characterized by the above mentionedtechniques and compared with standard Xaar actuators.

Abstract:
Abstract Distributed control of elastic shell continua using spatially distributed piezoelectric actuators is proposed and a generic distributed velocity feedback algorithm with a spatial modal feedback function formulated. The generic distributed modal feedback function is further represented by a gain factor and a spatially distributed orthogonal (mode shape) function to achieve independent modal actuation capability. Based on this principle, distributed piezoelectric actuators can be spatially shaped to emulate the spatial orthogonal actuation of the distributed modal feedback function. Distributed orthogonal shaped modal actuators for ring shells are proposed and their modal actuations demonstrated. Analyses suggested that the primary control action came from the in-plane membrane (circumferential) forces and that contributed by the bending control moment is relatively insignificant for lower natural modes. Control effects due to thickness variation of the ring shell and the actuator are also investigated.

Abstract:
In this paper, single crystal piezoelectric actuators are developed and demonstrated as a means of increasing actuator authority while maintaining strain precision for adaptive optics used large throw deformable mirror applications. Single crystal (PMN-PT crystal) stack actuators with foot print size of 5 mm × 5 mm and height varied from 16 mm to 21 mm have been designed, fabricated and tested. The actuation stroke larger than 50 μm is obtained under driving electric field of 15 KV/cm for single crystal stack actuators. In-plane actuation stroke is about 25 μm under 8KV/cm for single crystal plate actuators. The characterization results show that the single crystal piezoelectric actuators hold enhanced stroke and coupling coefficient (>0.83) under lower driving field comparing with PZT counterpart, while keep the nature of piezoelectric actuations with high precision, high resolution, fast response under high preload stress. The potential benefits of incorporating these actuators in a deformable mirror (DM) design were demonstrated by system modeling using the Integrated Optical Design Analysis Software (IODA) developed by SRS. The modeling shows that low order aberrations with peak to valley errors as large as 40 microns could be corrected to diffraction limited performance with a reasonable number of actuators and acceptable actuator forces and face sheet stresses. In the case of DM correction with 20 microns of 1st-Order Astigmatism-X error (Peak to valley: 38.74 μm, RMS error: 8.13 μm), the corrected wavefront error was reduced to PV of 0.26 μm and RMS error of 0.024 μm, which suggest promise for large throw DM applications.

Abstract:
Abstract A new type of functionally graded (FG) piezoelectric bending actuator was proposed by the authors in the former study and the advantage of the new actuator over the traditional bimorph and unimorph actuators in internal stress distribution was illustrated by simulation results. In this study, functionally graded piezoelectric bending actuator was designed and fabricated. The material compositions with different dielectric and piezoelectric constants were selected from the Pb(Ni1/3Nb2/3)O3-PbZrO3-PbTiO3 (PNN-PZ-PT) family and used as the four layers in the new FG piezoelectric actuator. The piezoelectric constant and dielectric constant were graded oppositely in the thickness direction. Stress distribution of the FG piezoelectric actuator under external voltage was analyzed using finite element method (FEM) and the simulation results showed the stress discontinuity of the new actuator is smaller than that of traditional bimorph actuator. Durability of the fabricated FG piezoelectric actuators was measured in a vibration test and compared with that of the traditional bimorph actuator to evaluate the improvement of performance. The results showed that the durability of the FG piezoelectric actuators is much higher than that of the bimorph actuator.

Abstract:
Microactuators provide controlled motion and force for applications ranging from RF switches to rate gyros. Large amplitude response in piezoelectric actuators requires amplification of their small strain. This paper studies the performance of a uniflex actuator in terms of its displacement and blocking force compared to uniflex and flextensional actuators. A uniflex microactuator combines the strain amplification mechanisms of a unimorph and flexural motion to produce large displacement and blocking force. Analytical models for displacement and blocking force for all the three actuators are used in optimization, to study their relative performance. The uniflex actuator outperforms both unimorph and flextensional actuators in displacement, but, the unimorph actuator generates more blocking force. The uniflex actuator can therefore be used in applications that demand higher displacement and lower blocking force compared to a unimorph actuator.

Abstract:
The cooling performance of piezoelectric actuators is evaluated for low-form-factor electronics in this work. A piezoelectric actuator is a cantilever made from metal or plastic with a piezoelectric material bonded to it. Under an alternating electrical current, the piezo actuator oscillates back and forth, generating airflow. Compared to conventional fans, these actuators have the advantages of low power consumption, low noise, and smaller dimensions. The parameters investigated in the experiments are actuator orientation, actuator-to-heat source distance, and actuator amplitude. For an actuator power consumption of 31 mW, the heat source temperature was lowered by more than 25°C compared to natural convection conditions (for a 2.45 W heater power dissipation). Performance comparisons against axial fans and natural convection heat sinks show that the piezo actuators perform significantly better in terms of power consumption and cooling volume. This paper was also originally published as part of the Proceedings of the ASME 2005 Heat Transfer Summer Conference.

Abstract:
A novel vibration control method utilizing magnetically mounted piezoelectric actuators is described. Piezoelectric actuators are bonded to permanent magnets, which are attached to the surface of a steel cantilever beam through their magnetic attraction. The magnetic-piezoelectric control mounts are an alternative to traditional epoxy attachment methods for piezoelectrics which allows easy in-the-field reconfiguration. In model and laboratory measurements, the beam is driven through base excitation and the resonant shunt and synchronized switching techniques are applied to two magnetic-piezoelectric control mounts to attenuate vibration. The coupled system is discretized using a Galerkin finite element model that incorporates relative axial motion between the beam and the mounts, which is governed by the sticking contact stiffness per unit length of the beam-magnet interface. The control mounts are designed using a magnetic array configuration which increases the attraction force for a given magnet thickness. Results show that the magnetic-piezoelectric control mounts provide attenuation, while also providing the flexibility to easily adjust the actuators along the length of the beam.
