Micro Electro Mechanical Systems (MEMS) have an extensive use in different areas of technology. Inertial sensors (accelerometers and gyroscopes) are one of the most widely used devices fabricated using MEMS technology. MEMS accelerometers play an important role in different application areas such as automotive, inertial navigation, guidance, industry, space applications etc. because of low cost, small size, low power, and high reliability. This book presents a detailed SIMULINK model for a conventional capacitive sigma-delta accelerometer system consisting of a MEMS accelerometer, closed-loop readout electronics, and signal processing units (e.g. decimation filters). By using this model, it is possible to estimate the performance of the full accelerometer system including individual noise components, operation range, open loop sensitivity, scale factor, etc. The developed model has been verified through test results using a capacitive MEMS accelerometer, full-custom designed readout electronics, and signal processing unit implemented on a FPGA.

Sensors and devices, based on micromachining technology, known as micro-electro-mechanicalsystems or MEMS, have been received increasing attention so far in recent years. Micromachined inertial sensors, consisting of accelerometers and gyroscopes, are one of the most important types of silicon-based sensor. MEMS capacitive accelerometers have been extensively used in automobiles, inertial navigation systems, earth quake detection and many other bio-medical applications. This book deals with the design of a monolithic 3DOF MEMS capacitive accelerometer using both analytical and numerical techniques. Monolithic accelerometer is a single structure having three individual single axis Accelerometers on a single substrate and utilizes a surface micromachining technology using standard PolyMUMPs process. The designed accelerometer is 3mm×3.1mm in size, has low mechanical noise floor, high sense capacitance and high sensitivity along in-plane (x and y) and out-of-plane (z) axes. Performing a detailed finite element analysis in ANSYS 11.o, physical level simulation has been done to verify the deflection for x, y and z axes with respect to the applied acceleration (g).

Exploring genomic functions requires accurate hysiological data acquisition to reveal the connection between genomic structure and medical symptoms. Most of these genetic experiments begin by changing certain genomic sequences of laboratory mice and then monitoring their physiological behavior. Physiological parameters typically include blood pressure, EKG, EEG, heart rate, body temperature, and body activity. In order to acquire accurate data with minimum distortion, a miniaturized wireless sensor without battery is highly desired. This work focuses on wireless activity sensor development. A lateral-axis differential capacitive MEMS accelerometer is designed and fabricated in MUMPs process. The system has been characterized with an untethered laboratory mouse. The received signal shows various acceleration waveforms corresponding to different types of mouse activities. The MEMS accelerometer and interface circuit can be potentially integrated with other biological sensors to achieve a miniature implantable biosensing system.
