The package and interconnection are critical concerns that influence the reliability of MEMS sensors applied in modern automotive under random vibration conditions. This paper conducts a research on this problem to reveal the reliability and influencing factors of MEMS on board level using finite element modelling and random vibration response simulation method. The ADXL78 MEMS chip is used as ...

Integrated GPS/INS systems provide an enhanced navigation system that has superior performance in comparison with either system operating in stand-alone mode as it can overcome each of their limitations. The high cost and government regulations prevent the wider inclusion of high quality IMUs to augment GPS as a commercialized navigation system in many navigation applications. The progress in M...

The majority of microelectromechanical system (MEMS) devices must be combined with integrated circuits (ICs) for operation in larger electronic systems. While MEMS transducers sense or control physical, optical or chemical quantities, ICs typically provide functionalities related to the signals of these transducers, such as analog-to-digital conversion, amplification, filtering and information ...

Process planning for a MEMS device is almost always conducted manually by the designer to date. As the structures of MEMS devices become more and more complicated, in order to release the designers from the hard and tedious work and speed up the development of MEMS products, such a situation should be changed. In this study, a solid based CAPP method for surface micromachined MEMS device is pre...

A new approach to wideband and smart re-configurable antennas using RF MEMS switches and fractal antennas is presented. Index Terms – Smart antennas, wideband, fractals, RF-MEMS.

We report a MEMS (Micro-Electro-Mechanical Systems)-based microbial fuel cell (MFC) that produces a high power density. The MFC features 4.5-μL anode/cathode chambers defined by 20-μm-thick photo-definable polydimethylsiloxane (PDMS) films. The MFC uses a Geobacter-enriched mixed bacterial culture, anode-respiring bacteria (ARB) that produces a conductive biofilm matrix. The MEMS MFC generated ...

We are developing physical design tools for surfacemicromachined MEMS, such as polysilicon microstructures built using MCNC’s Multi-User MEMS Process service. Our initial efforts include automation of layout synthesis and behavioral simulation from a MEMS schematic representation. As an example, layout synthesis of a folded-flexure electrostatic combdrive microresonator is demonstrated. Lumpedp...

A Fourier transform spectrometer (FTS) that incorporates a closed-loop controlled, electrothermally actuated microelectromechanical systems (MEMS) micromirror is proposed and experimentally verified. The scan range and the tilting angle of the mirror plate are the two critical parameters for MEMS-based FTS. In this work, the MEMS mirror with a footprint of 4.3 mm × 3.1 mm is based on a modified...
