High performance, micro-g resolution, small size, low cost, low power accelerometers are needed in many applications such as inertial navigation, Unmanned Aerial Vehicles (UAVs), and GPS augmentation. Several sensing methods have been used, including piezoresistive/electric, resonant, tunneling, and capacitive techniques. Capacitive sensing has several advantages in terms of high sensitivity, stable DC-characteristics, low power dissipation, low temperature sensitivity, and low noise floor. This research work demonstrates full functionality of high- sensitivity, low-noise capacitive multi-axis accelerometers. In order to achieve micro-g resolution, two different structures have been utilized: a Silicon-On-Glass (SOG) accelerometer, and an all-silicon accelerometer. A monolithic fabrication technique for Post-CMOS MEMS is also developed. Finally, a 3-axis single-chip accelerometer is presented. The 3-axis accelerometer shows 3pF/g sensitivity and sub- g/rtHz mechanical noise floor. The 3-axis accelerometer with the readout circuit provides noise floor of 1.6 g/rtHz and 1.1 g/rtHz for in-plane and out-of- plane devices, respectively.

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).

Quad rotors are types of unmanned air vehicles that became an attractive topic to an enormous number of people worldwide. This book focuses on sensor fusion of low-cost inertial sensors: a tri-axis accelerometer, a tri-axis gyroscope and a tri-axis magnetometer. Three types of filters were implemented in this book: two models of linear complementary filter (LCF), two models of linear Kalman filter (KF) and a quaternion-based extended Kalman filter (EKF). A total of five filter models were tested and verified using experimental data sets through three distinct scenarios. Six different data sets were chosen, each with antithetic characteristics, to test the filters on them. On the basis of the results of this research, it can be concluded that taking into consideration accelerometer bias improves the performance of the filter. KF shows the best performance as it combines the characteristics of short computing time and accurate estimation results suiting the aim of the book which is to allow the quad rotor to hover.
