Abstract:

The significant advancements within the electronics miniaturization field have shifted the scientific interest towards a new class of precision devices, namely microelectromechanical systems (MEMS). Specifically, MEMS refers to microscaled precision devices generally produced through micromachining techniques that combine mechanical and electrical components for fulfilling tasks normally carried out by macroscopic systems. Although their presence is found throughout all the aspects of daily life, recent years have witnessed countless research works involving the application of MEMS within the biomedical field, especially in drug synthesis and delivery, microsurgery, microtherapy, diagnostics and prevention, artificial organs, genome synthesis and sequencing, and cell manipulation and characterization. Their tremendous potential resides in the advantages offered by their reduced size, including ease of integration, lightweight, low power consumption, high resonance frequency, the possibility of integration with electrical or electronic circuits, reduced fabrication costs due to high mass production, and high accuracy, sensitivity, and throughput. In this context, this paper aims to provide an overview of MEMS technology by describing the main materials and fabrication techniques for manufacturing purposes and their most common biomedical applications, which have evolved in the past years.

Abstract:

An attempt has been made to summarize some of the important developments in the emerging technology of microelectromechanical systems (MEMS) from the mechanical engineering perspective. In the micro domain, design and fabrication issues are very much different from those of the macro world. The reason for this is twofold. First, the limitations of the micromachining techniques give way to new exigencies that are nonexistent in the macromachinery. One such difficulty is the virtual loss of the third dimension, since most of the microstructures are fabricated by integrated circuit based micromachining techniques that are predominantly planar. Second, the batch-produced micro structures that require no further assembly, offer significant economical advantage over their macro counterparts. Furthermore, electronic circuits and sensors can be integrated with micromechanical structures. In order to best utilize these features, it becomes necessary to establish new concepts for the design of MEMS. Alternate physical forms of the conventional joints are considered to improve the manufacturability of micromechanisms and the idea of using compliant mechanisms for micromechanical applications is put forth. The paper also reviews some of the fabrication techniques and the micromechanical devices that have already been made. In particular, it discusses the fabrication of a motor-driven four-bar linkage using the “boron-doped bulk-silicon dissolved-wafer process” developed at The University of Michigan’s Center for Integrated Sensors and Circuits.

Abstract:

This paper proposes a very high sensitivity pressure sensor with a novel technique for temperature compensation. The proposed technique employs a geometrical method for self-compensation of Young’s modulus reduction due to temperature increase, where a stronger spring with much larger length and width is anchored. According to the connection of the suspension spring to the larger spring, in higher temperatures, the large spring experiences more length increase, which in turn increases the stiffness of the suspension spring and, consequently, could compensates the Young’s modulus reduction. Simulation results verify that the temperature variation related error in the compensated sensor is less than 0.66% of full-scale under 260 ℃ of temperature range, which shows considerable improvement in comparison with literature. The total consumed area is about 0.033 mm2 with the sensitivity of 290 × 10−6 K−1.

Abstract:

Abstract: Optical communication systems are the premier conduit for providing broadband data across continents, nations, cities, neighborhoods, and are now starting to penetrate into private homes. This spectacular achievement is the culmination of years of research and development efforts in diverse fields. Recently we are witnessing the evolution of these communication systems towards optical networking. The advent of optical networking has been enabled by a suite of complementary optical subsystems that are pivotal to the operation and management of these networks. These optical microsystems directly interact with the optical signal and-through functionality afforded by design-are able to filter, switch, attenuate, and adapt the optical communication channels carried by the network. In this talk I will review a sampling of these enabling devices and focus on the MEMS technology required for its implementation.

Abstract:

Currently, the technology of microelectromechanical systems is widely used in the development of high-frequency and ultrahigh-frequency devices. The most important requirements for modern and advanced devices of the ultra-high-frequency range are the reduction of weight and size characteristics, power consumption with an increase in their functionality, operating frequency and level of integration. Radio frequency microelectromechanical switches are developed using the technology of the manufacture of CMOS-integrated circuits. Integrated radio frequency control circuits require low control voltages, the high ratio of losses to the isolation in the open and closed condition, high performance and reliability. This review is devoted to the analytical approach based on the knowledge of materials, basic performance indices and mechanisms of failure, which can be used in the development of radio-frequency microelectromechanical switches.

Abstract:

The strong adherence (stiction) of adjacent surfaces is a major design concern in microelectromechanical systems (MEMS). Advances in micromachine technology greatly depend on basic understanding of microscale stiction phenomena. An analysis of the different stiction micromechanisms and the elastic deformation of asperities at MEMS interfaces is developed using a two-dimensional fractal description of the surface topography. The fractal contact model is scale independent since it is based on parameters invariant of the sample area size and resolution of measuring instrument. The influence of surface roughness, relative humidity, applied voltage, and material properties on the contributions of the van der Waals, electrostatic, and capillary forces to the total stiction force is analyzed in light of simulation results. It is shown that the effects of surface roughness and applied voltage on the maximum stiction force are significantly more pronounced than that of material properties. Results for the critical pull-off stiffness versus surface roughness are presented for different material properties and microstructure stand-free surface spacings. The present analysis can be used to determine the minimum stiffness of microdevices required to prevent stiction in terms of surface roughness, apparent contact area, relative humidity, applied voltage, and material properties.

Abstract:

Microscale biaxial accelerometers are required to be sensitive to applied accelerations and manufacturable by means of microelectromechanical systems technology. In order to meet these requirements, a compliant realization of biaxial accelerometers, dubbed simplicial biaxial accelerometers, has been proposed, as reported in this paper. Notched joints, to realize what is termed Π-joints in the parallel-robots literature, are employed and then improved by the introduction of Lamé-shaped hinges serving as flexible joints. The sensitivity of the simplicial biaxial accelerometers in estimating accelerations is investigated and validated by means of finite element analysis. The sensing system is embedded in the simplicial biaxial accelerometers, with piezoresistive sensing technology adopted in the instrumentation design. Using the principles of piezoresistive sensing, the electronic layout is developed for the accelerometer. Through the piezoresistive analysis implemented on the finite element model of the simplicial biaxial accelerometers, the matrix that maps voltage signals into acceleration signals is derived. By virtue of both the structural and electronic designs, the accelerometer is observed to be sensitive to accelerations in its plane, but fairly insensitive to accelerations in any of the other four directions of the rigid-body motion. Finally, prototypes were fabricated with microelectromechanical systems technology to test the microfabrication feasibility of the structure and measurement system of the accelerometer. Test results are the subject of a forthcoming paper.

Abstract:

Radio-frequency switches manufactured by microelectromechanical systems technology are now widely used in aerospace systems and other mobile installations for various purposes. In these operating conditions, these devices are often exposed to intense mechanical environmental influences that have a strong impact on their operation. These negative effects can lead to unwanted short-circuit or open-circuit in the radio-frequency transmission line or to irreversible damage to structural elements. Such a violation in the operation of radio-frequency microelectromechanical switches leads to errors and improper functioning of the electronic equipment in which they are integrated. Thus, this review is devoted to the analysis of the origin of these negative intense mechanical effects of the environment, their classification, and analysis, as well as a review of methods to reduce or prevent their negative impact on the design of radio-frequency microelectromechanical switches.

Abstract:

The lab-on-a-chip (LOC) technology was expected to influence our every day live in a similarly fundamental way as integrated circuits have. Unfortunately, this demand has not been met yet. The cause therefore lies in the complexity of microelectromechanical systems (MEMS), which form the base of the current LOC technology. We present a new concept of LOC which are based on fluidic microchemomechanical systems (μCMS). During the fabrication process, these μCMS are preprogrammed by monolithic integration of special active components. These active components are holding chemical energy that can be transformed at least once into mechanical energy and thus provide a timed and quantitative exactly defined fluidic function. With our simple and inexpensive fabrication method combined with the above mentioned advantages of the invented μCMS, new and better LOC technology can be developed.

Abstract:

A novel die-sinking micro-electro discharge machining (EDM) process is presented for volume fabrication of metallic microcomponents. In the process, a high-precision silicon electrode is fabricated using deep reactive ion etching (DRIE) process of microelectromechanical systems (MEMS) technology and then coated with a thin layer of copper to increase the conductivity. The metalized Si electrode is used in the EDM process to manufacture metallic microcomponents by imprinting the electrode onto a flat metallic surface. The two main advantages of this process are that it enables the fabrication of metallic microdevices and reduces manufacturing cost and time. The development of the new EDM process is described. A silicon component was produced using the Surface Technology Systems plasma etcher and the DRIE process. Such components can be manufactured with a precision in nanometres. The minimum feature of the component is 50 μm. In the experiments, the Si component was coated with copper and then used as the electrode on an EDM machine of 1 μm resolution. In the manufacturing process, 130 V and 0.2 A currents were used for a period of 5 min. The SEM images of the resulting device show clear etched areas, and the electric discharge wave chart indicates a good fabrication condition. The experimental results have been analysed and the new micro-EDM process is found to be able to fabricate 25 μm features.

Flies use so-called halteres to sense body rotation based on Coriolis forces for supporting equilibrium reflexes. Inspired by these halteres, a biomimetic gimbal-suspended gyroscope has been developed using microelectromechanical systems (MEMS) technology. Design rules for this type of gyroscope are derived, in which the haltere-inspired MEMS gyroscope is geared towards a large measurement bandwidth and a fast response, rather than towards a high responsivity. Measurements for the biomimetic gyroscope indicate a (drive mode) resonance frequency of about 550 Hz and a damping ratio of 0.9. Further, the theoretical performance of the fly's gyroscopic system and the developed MEMS haltere-based gyroscope is assessed and the potential of this MEMS gyroscope is discussed.

Abstract:

Etching the large area of sacrificial layer under the microstructure to be released is a common method used in microelectromechanical systems technology. In order to completely release the microstructures, many etching holes are often required on the microstructure to enable the etchant to completely etch the sacrificial layer. However, the etching holes often alter the electromechanical properties of the micro devices, especially capacitive devices, because the fringe fields induced by the etching holes can significantly alter the electrical properties. This article is aimed at evaluating the fringe field capacitance caused by etching holes on microstructures. The authors aim to find a general capacitance compensation formula for the fringe capacitance of etching holes by the use of ANSYS simulation. According to the simulation results, the design of a capacitive structure with small etching holes is recommended to prevent an extreme capacitance decrease. In conclusion, this article provides a fringing field capacitance estimation method that shows the capacitance compensation tendency of the design of etching holes; this method is expected to be applicable to the design in capacitive devices of complementary metal oxide semiconductor–microelectromechanical systems technology.

Abstract:

One of the valuable problems of modern science and technology is to create a low-power (less than 1 mW), long-life (10-100 years) miniature sources of electric power based on the conversion of radioactive isotopes of energy into electricity. Such batteries can be used directly, for example, in cardiology, microelectromechanical systems (MEMS), in military equipment and power sharing systems for many applications. Among isotopes to create energy sources particular interest is nickel Ni63, as it is safe for human health and thus in the development of electric batteries based on it devoted a lot of work. This article discusses the main types of structures betavoltaic battery (BVB) with the prospects for industrial application using - isotope of nickel Ni63. It is shown that the efficiency of beta radiation conversion of into electricity and the dimensions of the existing batteries are far from the theoretically possible. It is shown that the prospects for improving the effective efficiency are planar multijunction betavoltaic batteries.

Abstract:

Micromachined planar orifice nozzles have been developed using MEMS (micro-electro-mechanical systems) technology and tested with commercially produced diesel injection systems. Such a system, properly designed, may have the capability to improve the spray characteristics in DI diesel engines due to improved atomization and fuel-air mixing. To demonstrate this process, 14 microplanar orifice nozzles were fabricated with deep X-ray lithography and electroplating (LIGA) technology. The circular orifice diameters were varied from 40 to 260 microns and the number of orifices varied from one to 169. Three plates with noncircular orifices were also fabricated to examine the effect of orifice shape on spray characteristics. These nozzles were then attached to commercial diesel injectors and the associated injection systems were used in the study of drop sizes. The experiments were carried out at two different injection pressures (around 25 MPa and 80 MPa). Local drop sizes were measured by a laser diffraction technique, and the average drop sizes of the whole sprays were measured by a light extinction technique. The drop sizes were found to depend primarily on the total mass flow area. Coalescence droplet collisions among adjacent sprays were apparent for the multiple orifice nozzles. Nonplanar configurations are under development and may show improved performance.

Abstract:

This paper presents a photonic polarization switch based on microelectromechanical systems (MEMS) technology. The polarization switch can change the pathway of the different polarized light via optical tunneling effects. By controlling the incident angle of the input light, the output polarization state can be switched between two different polarization states. The polarization switch has promising applications on both photonic circuit and bio-detecting.
