Surface processes in MEMS technology
free download
This review focuses on the problem of adhesion in microelectromechanical systems and on the application of the principles and techniques of surface science to understand and manipulate, at the atomic level, the interfacial forces which are responsible for strong
Calibration of a MEMS inertial measurement unit
free download
An approach for calibrating a low-cost IMU is studied, requiring no mechanical platform for the accelerometer calibration and only a simple rotating table for the gyro calibration. The proposed calibration methods utilize the fact that ideally the norm of the measured output of
Dry silicon etching for MEMS
free download
Silicon etching is an essential process step for the fabrication of micro-electro-mechanical systems ( MEMS ). As we enter the on-chip integrated sensor era, the sensing elements are typically defined after circuit fabrication. This has benefits in permitting the use of a standard

3D coupled electro-mechanics for MEMS : applications of CoSolve-EM
free download
Micro-electro-mechanical systems ( MEMS ) are often designed on scales at which electrostatic forces are capable of moving or deforming the parts of the system. In this regime accurate prediction of device behavior require 3D coupled simulations between the
Electrostatic pull-in test structure design for in-situ mechanical property measurements of microelectromechanical systems ( MEMS )
free download
M-TEST, an electrostatic pull-in approach for the in-situ mechanical property measure ments of microelectromechanical systems ( MEMS ), is used to extract the Youngs modulus and residual stress in polysilicon surface micromachined devices. Its high sensitivity to
Failure mechanisms in MEMS

This research aims at enhancing the accuracy of land vehicular navigation systems by integrating GPS and Micro-Electro-Mechanical-System ( MEMS ) based inertial measurement units (IMU). This comprises improving the MEMS -based inertial output signals as well as
Mems accelerometers
free download
MEMS accelerometers are one of the simplest but also most applicable micro- electromechanical systems. They became indispensable in automobile industry, computer and audio-video technology. This seminar presents MEMS technology as a highlyThings, but, apart from being perhaps too playful a title, we didnt like the word big in it. Thats because the book was intended to be an introduction to the world of science and engineering at the microscale, not a comprehensive treatment of the field at large. Other
