Advances in micromachining techniques have led to the evolution of micro-electromechanical systems (MEMS). These techniques are typically based on semiconductor manufacturing processes, which offer various advantages such as batch manufacturing of miniaturized devices and monolithic integration of microelectronics with the devices. Surface micromachining has been used to construct complex micro...
The aim of this work is to develop a lowoverhead, low-cost built-in test for Micro Electro Mechanical Systems (MEMS). The proposed method relies on processing the Impulse Response (IR) through trained neural networks, in order to predict a set of MEMS performances, which are otherwise very expensive to measure using the conventional test approach. The use of neural networks allows us to employ ...
Abstract The NiCr micro-heater is a key element of MEMS-based electro-explosive device (mEED), while electrostatic discharge (ESD) may excite the accidentally. To discover mechanism that how ESD excitations effect on heat response performance micro-heater, electro-thermal conversion process was numerically modelled by using commercial software. Three different shapes micro-heaters, including re...
In recent years, a very large amount of scientific work has been achieved around Micro-Electro-Mechanical Systems (MEMS). Some industrial success stories (accelerometers, gyroscopes and MOEMS) have shown their maturity. MEMS are now starting to take place around us in our everyday life as the microelectronic did 20 years ago. However, a lot of effort is still needed for the integration of ICs a...

In this work the reliability of a Micro-Electro-Mechanical Systems (MEMS) microphone is studied through two accelerated life tests, mixed flowing gas (MFG) testing and shock impact testing. The objective is to identify the associated failure mechanisms and improve the reliability of MEMS devices. Failure analyses are carried out by using various tools, such as optical microscopy, scanning elect...
Micro-mirror arrays are currently being developed by a number of companies for optical switching. To bring these products to the market quickly, a rapid development cycle is needed, leaving little time for multiple fabrication runs. CAD tools for MEMS can reduce the number of fabrication iterations run by allowing prototyping to occur within the virtual environment. Here, many models can be tes...
The mechanical behaviors of microstructures and micro-devices have drawn the attention from researchers on materials and mechanics in recent years. To understand the rule of these behaviors, the deformation measurement techniques with micro/nanometer sensitivity and spatial resolution are required. In this paper, a micro-marker identification method is developed to measure microstructure deform...
As a result of the unpredictable nature extreme environments (including temperature, humidity, impact, and other factors), micro-electro-mechanical systems (MEMS) solid-state fuze control modules have an urgent requirement for MEMS switch (MEMS-S3). In particular, this must remain stable without any energy input after state transition (i.e., it be bistable). paper, bistable (MEMS-bS3) is design...
