Abstract:

AbstractThe microfabrication and packaging of novel, three-dimensional, polyimide-based, highly flexible, microscale electrocorticography multi-electrode arrays for enhanced epicortical recording of local field potentials is presented. A polyimide foil embeds metallic structures relating to 32 taper-type electrode sites, contact pads as well as interconnecting conductor paths which are integrated in the planar portion of the electrode substrate material. Circular exposed and, thus, active electrode sites are 50 μm in diameter and employed center-to-center pitches range from 250 μm to 1 mm, respectively. As-fabricated 3D-μECoG-MEAs provide taper heights of approximately 4 μm as well as 59 μm being distinguished by characteristic impedances of about 368.9 kΩ at 1 kHz measured in saline electrolyte. The applied packaging strategies favor flip-chip bonding and vapor phase soldering of the polymer substrates to customized printed circuit boards.

Abstract:

A sequence of RAO first-pass studies (first with 99mTc and then twice with 195mAu) was performed in 18 normal volunteers and in 12 CAD patients using two different types of collimator for medium energy: a standard collimator (MEMS) and a special high-sensitivity collimator (MEHS). The following data were compared: the peak count rate, the net LV end-diastolic counts and the LVEF. Using MEMS the end-diastolic counts acquired were so low (12% of 99mTc average value) that EF standard deviation had a mean value of 0.061 (range 0.045-0.081). With MEHS the following results were obtained: 1. the peak count rate and LV net end-diastolic counts with 195mAu were 55% and 50% respectively, of 99mTc values; 2. a good correlation was shown between LVEF values either with 99mTc and 195mAu (r =.97), or with 195mAu sequential studies (r =.98).

Abstract:

The first issue raised by this paper is whether semiotics can bring any added value to ecology. A brief examination of the epistemological status of semiotics in its current forms suggests that semiotics' phenomenological macroconcepts are incommensurate with the complexity of the sciences comprising ecology and are too reductive to usefully map the microprocesses through which organisms evolve and interact. However, there are at least two grounds on which interfacing semiotics with ecology may prove to be scientifically productive: the very looseness of semiotic discourse can be an important catalyser for multidisciplinary interactions, an important condition for the emergence of truly holistic ecology; the present semiotic conceptual apparatus is not carved in stone. All its notions, frames of reference and types of reasoning can evolve in contact with the problems encountered in evolutionary ecological research. Semiotics, as an open-ended epistemological project, remains a proactive intellectual resource. The second issue raised by this paper is precisely to call attention to the opportunity provided by recent developments for rethinking and furthering semiotic inquiry. An attempt is made to show that counterintuitive theories such as memetics and new frontiers in teclmology such as nanotechnology, could help recast ecosentioticsalong more intellectually exciting lines of inquiry than the mere rewriting of ecological discourse in terms of the traditional semiotic macroconcepts. It goes without saying that memetics and nanotechology are not presented here as definitive solutions but simply as indicative of possible directions toward acomprehensive evolutionary ecosentiotics that would radically transform the basis of the 20th century sentiotic discourse and its ideological agenda.

Abstract:

This paper presents a discussion of some of the major issues that need to be considered for the successful commercialization of MEMS products. The diversity of MEMS devices and historical reasons have led to scattered developments in the MEMS manufacturing infrastructure. A good manufacturing strategy must include the complete device plan including package as part of the design and process development of the device. In spite of rapid advances in the field of MEMS there are daunting challenges that lie in the areas of MEMS packaging, and reliability testing. CAD tools for MEMS are starting to get more mature but are still limited in their overall performance. MEMS manufacturing is currently at a fragile state of evolution. In spite of all the wonderful possibilities, very few MEMS devices have been commercialized. In our opinion, the magnitude of the difficulty of fabricating MEMS devices at the manufacturing level is highly underestimated by both the current and emerging MEMS communities. A synopsis of MEMS manufacturing issues is presented here.

Abstract:

With the fast development of the fifth-generation cellular network technology (5G), the future sensors and microelectromechanical systems (MEMS)/nanoelectromechanical systems (NEMS) are presenting a more and more critical role to provide information in our daily life. This review paper introduces the development trends and perspectives of the future sensors and MEMS/NEMS. Starting from the issues of the MEMS fabrication, we introduced typical MEMS sensors for their applications in the Internet of Things (IoTs), such as MEMS physical sensor, MEMS acoustic sensor, and MEMS gas sensor. Toward the trends in intelligence and less power consumption, MEMS components including MEMS/NEMS switch, piezoelectric micromachined ultrasonic transducer (PMUT), and MEMS energy harvesting were investigated to assist the future sensors, such as event-based or almost zero-power. Furthermore, MEMS rigid substrate toward NEMS flexible-based for flexibility and interface was discussed as another important development trend for next-generation wearable or multi-functional sensors. Around the issues about the big data and human-machine realization for human beings’ manipulation, artificial intelligence (AI) and virtual reality (VR) technologies were finally realized using sensor nodes and its wave identification as future trends for various scenarios.

Abstract:

Many types of MEMS devices have been fabricated through electro- or electroless-plating of metals, such as Ni. Typically, this is accomplished using LIGA or LIGA-like processes where the metal is plated into a mold fabricated through patterning a photoimageable polymeric layer. After plating, the polymeric mold is removed though chemical etching or ashing, leaving the freestanding metal structure. Through the advent of TSV technology, techniques have been developed for plating Cu into DRIE etched vias in Si wafers. This technology has matured to the point where arrays of defect free plated Cu vias can be realized across the surface of the Si wafer. TSVs generally require small diameter Cu posts extending through the depth of the Si wafer between a bond pad on each surface. However, this technology can be modified to filling other types of DRIE etched features with plated Cu to realize complex 3D Cu microstructures in and on the Si wafer. Furthermore, the Si die containing these Cu structures can be eutectically bonded to other surfaces, such as pads on printed circuit boards. Then the Cu structure can be released from the bulk Si though exposing it to XeF2 gas in a low vacuum. This gas chemically converts solid Si to gaseous SiF2, but is nonreactive with most other materials, including Cu, SiO2 and E-glass. After the bulk Si has been removed through this process, the free standing Cu microstructure remains, attached to the substrate to which it was eutectically bonded. A variety of MEMS devices can be realized with this technique, such as antennas, inductors, air gap capacitors, sensors and electrostatic actuators.

Abstract:

This paper elaborates increasing use of microelectromechanical systems (MEMS) in aerospace industry. MEMS are chip-size devices usually carved from semiconductor wafers. Jet engines running lean fuel mixtures are prone to instability. High-temperature MEMS sensors could improve performance and fuel mileage while reducing emissions. The paper also discusses different MEMS structures, as MEMS structures vary greatly. The oscillating proofmass structures sense angular rotation around an axis in the gyro on the right. The industry has also begun to build a more innovation-ready infrastructure. The MEMS and Nanotechnology Exchange provides another way to ease the tortuous path to commercialization. It promises more prototypes, and more technologies will flow from MEMS inventors in the future. However, experts believe that the real problem is that until more MEMS companies begin making money in aerospace, venture capitalists hesitate to fund their companies.

Abstract:

The questions of assessment of achievable performance values of the integrated inertial-satellite navigation system complexed with odometer sensor and used for ground transport and agricultural technological vehicle are considered. Construction of relatively cheap modern navigation systems for ground transport and agricultural technological vehicles is provided by integrating diverse navigation systems, which include inertial-satellite systems that combine into a single hardware system the inertial and satellite modules. Achievable accuracy of gaining the navigation parameters is achieved by using special algorithms for processing of measurement information in combination with complexion of the system with an external source of additional information, where odometer sensor belongs. The most promising sensors are sensors, built using the technology of production of microelectromechanical systems - MEMS / MEMC (Micro-Electro Mechanical Systems). The navigation systems based on MEMS sensors have several advantages. The main advantages are small weight and size characteristics (volume less 1sm3, and weighs less than 1 gram), low power consumption, high reliability, resistance to vibro-impact loads (up to 2000g), easy integration of sensors and electronic modules of the navigation system, low cost. The main disadvantage is the need for the synthesis of complex algorithms of processing of measuring information to obtain the desired accuracy of the estimate of navigation parameters. The navigation system, where as MEMS sensors were used gyroscopes ADXRS-150 in conjunction with accelerometers ADXL-210 manufactured by Analog Devices, was considered. The main design and technological characteristics of sensors were shown, the selection criteria for sensors were formulated, technical and economic effect assessment of the use of MEMS in the navigation system is provided. The practical importance has the estimation of achievable accuracy characteristics of system under actual operating conditions. The paper presents the results of field tests of the navigation system based on MEMS sensors and designed for forklift carrying out transportation in the sea port. The results of experimental studies confirmed the effectiveness of the MEMS application as a sensing element of inertial-satellite navigation system of ground transport and agricultural technological vehicle that creates the foundation for the new high-tech developments.

Abstract:

Abstract The Micro-Electro-Mechanical Systems Fabry-Perot (MEMS-FP) filter is a pivotal photosensitive component within optical instrumentation, serving an integral role across various optical applications, including frequency selection spectroscopy and spectral analysis. The advent of MEMS-FP technology has significantly contributed to advancements in the optical field, underscoring the necessity for precise pre-fabrication theoretical predictions of device properties through finite element analysis (FEA). Nonetheless, the complexity inherent in three-dimensional modelling of MEMS-FP structures, coupled with the intricate nature of finite element simulations, presents substantial challenges that impede progress in MEMS-FP research. To navigate these challenges, this paper introduces a novel approach employing reinforcement learning (RL) for the automated design of MEMS-FP devices. This method encompasses the development of a Deep Q-Network (DQN) algorithm, the formulation of a tailored reward function, and an innovative strategy for updating the status of MEMS-FP devices. Various designs schemes of MEMS-FP devices can be acquired using MEMS-FP state search. The disparity between the MEMS-FP device design scheme and performance index can be assessed using a reward function. The DQN algorithm is crafted to update the network responsible for predicting Q-values. The agent trained by our method can rapidly calculate the MEMS-FP device design scheme that fulfils a specified performance index when provided with the performance index of the MEMS-FP device. By amalgamating reinforcement learning with MEMS-FP device research, this approach adeptly identifies optimal design configurations that meet specified performance criteria with enhanced precision and efficiency and promote the advancement of MEMS-FP devices.

Abstract:

Packaging of MEMS has been identified as one of the most significant areas of research for enabling MEMS usage in product applications. In order to make MEMS a real-life opportunity, it is vital to explore and develop an understanding of the possibilities and limitations of MEMS packaging. This paper presents several packaging structures for RF MEMS switch which based on GaAs substrate. The return loss of X-band RF MEMS switch before and after packaged can be simulated by Ansoft HFSS. The results show that return loss of RF MEMS switch after packaging deteriorated at least 3dB compared with that of before. Thermal mismatch caused by the variation of the temperature in the packaging process will introduce additional thermo-elastic strain and geometric deformation into the mechanical structure. The influence on return loss of the RF MEMS switch is researched in this paper too. Considering that, return loss simulated by HFSS decreases from -16.38dB to -16.88dB. Then, some design guidelines of RF MEMS packaging derived from the simulation of HFSS are also concluded at the end of the article.

Abstract:

MEMS-based LiDAR (micro-electro–mechanical system based light detection and ranging), with a low cost and small volume, becomes a promising solution for the two-dimensional (2D) and three-dimensional (3D) optical imaging. A semi-coaxial MEMS LiDAR design, based on a synchronous MEMS mirror pair, was proposed in our early study. In this paper, we specifically reveal the synchronization method of the comb-actuated MEMS mirror pair, including the frequency, amplitude, and phase synchronization. The frequency sweeping and phase adjustment are simultaneously implemented to accelerate the MEMS mirror synchronization process. The experiment is set up and the entire synchronization process is completed within 5 s. Eventually, a one-beam MEMS LiDAR system with the synchronous MEMS mirror pair is set up and a LiDAR with a field of view (FOV) of 60°, angular resolution of 0.2°, and frame rate of 360 Hz is obtained. The experimental results verify the feasibility of the MEMS mirror synchronization method and show a promising potential application prospect for the MEMS LiDAR system.

Abstract:

Vacuum packaging is very important for some micro-electro-mechanical systems (MEMS) devices to perform their basic functions properly and to enhance their reliability by keeping these devices away from harmful external environment. In order to maintain high vacuum in a cavity of MEMS devices, residual gases and leaking gases must be eliminated by embedded getter materials. Micro/Nano film getters absorbing gases inside the tiny cavity of MEMS packaging were introduced in this paper. The fabrication and characterization of micro/nano getters for MEMS applications were also presented. Various kinds of patterned getter films were prepared for different MEMS applications. The activation temperature and sorption capacity of the nonevaporable getter (NEG[1]) films was investigated. The formation of micro/nano films on the inner surface of MEMS devices is totally compatible with Si-based MEMS process and illustrates the applicability of the technique in vacuum maintenance of MEMS devices.

Abstract:

MEMS technology has become the hotspot of fuze development currently, but the reliability problems seriously influence the application of MEMS in fuze. By way of analyzing the characteristic of MEMS fuze mechanism in aspects of process technics, material behavior, structure form and micro size effect, it shows that the reliability of MEMS mechanism is quite different from the traditional fuze. The environment stress in full life cycle of fuze and the main failure mode of MEMS mechanism under environment stress have been analyzed, and the interrelated matrix between environment stress and failure mode has been presented. Based on these investigation, the reliability testing method of MEMS fuze mechanism has been studied, which can provide guidance for the reliability testing of MEMS fuze mechanism.

Abstract:

Micromirrors based on micro-electro-mechanical systems (MEMS) technology are widely employed in different areas, such as optical switching and medical scan imaging. As the key component of MEMS LiDAR, electromagnetic MEMS torsional micromirrors have the advantages of small size, a simple structure, and low energy consumption. However, MEMS micromirrors face severe disturbances due to vehicular vibrations in realistic use situations. The paper deals with the precise motion control of MEMS micromirrors, considering external vibration. A dynamic model of MEMS micromirrors, considering the coupling between vibration and torsion, is proposed. The coefficients in the dynamic model were identified using the experimental method. A feedforward sliding mode control method (FSMC) is proposed in this paper. By establishing the dynamic coupling model of electromagnetic MEMS torsional micromirrors, the proposed FSMC is evaluated considering external vibrations, and compared with conventional proportion-integral-derivative (PID) controls in terms of robustness and accuracy. The simulation experiment results indicate that the FSMC controller has certain advantages over a PID controller. This paper revealed the coupling dynamic of MEMS micromirrors, which could be used for a dynamic analysis and a control algorithm design for MEMS micromirrors.

Abstract:

Abstract Small, lightweight, power-efficient and low-cost microelectromechanical system (MEMS) inertial sensors and microcontrollers available in the market today help reduce the instability of Multibeam Sonars. Current MEMS inertial measurement units (IMUs) come in many shapes, sizes, and costs - depending on the application and performance required. Although MEMS inertial sensors offer affordable and appropriately scaled units, they are not currently capable of meeting all requirements for accurate and precise attitudes, due to their inherent measurement noise. The article presents the comparison of different MEMS technologies and their parameters regarding to the main application, namely Multibeam Echo Sounders (MBES). The quality of MEMS parameters is crucial for further MBES record-processing. The article presents the results of undertaken researches in that area, and these results are relatively positive for low-cost MEMS. The paper undertakes some vital aspect of using MEMS in the attitude and heading reference system (AHRS) context. The article presents a few aspects of MEMS gyro errors and their estimation process in the context of INS processing flow, as well as points out the main difficulties behind the INS when using a few top MEMS technologies.
