This thesis develops next-generation multi-degree-of-freedom gyroscopes and inertial measurement units (IMU) using micro-electromechanical-systems (MEMS) technology. It covers both a comprehensive study of the physics of resonator gyroscopes and novel micro/nano-fabrication solutions to key performance limits in MEMS resonator gyroscopes. Firstly, theoretical and experimental studies of physical phenomena including mode localization, nonlinear behavior, and energy dissipation provide new insights into challenges like quadrature errors and flicker noise in resonator gyroscope systems. Secondly, advanced designs and micro/nano-fabrication methods developed in this work demonstrate valuable applications to a wide range of MEMS/NEMS devices. In particular, the HARPSS+ process platform established in this thesis features a novel slanted nano-gap transducer, which enabled the first wafer-level-packaged single-chip IMU prototype with co-fabricated high-frequency resonant triaxial gyroscopes and high-bandwidth triaxial micro-gravity accelerometers. This prototype demonstrates performance amongst the highest to date, with unmatched robustness and potential for flexible substrate integration and ultra-low-power operation. This thesis shows a path toward future low-power IMU-based applications including wearable inertial sensors, health informatics, and personal inertial navigation.

This book focuses on gyro-free inertial navigation technology, which is used to measure not only linear motion parameters but also angular rates. Since no gyroscopes are used, the key technologies, such as initial alignment, attitude resolution, and error calibration, are very different than those used in traditional methods. Discussing each key technology in gyro-free inertial navigation system (GFINS) manufacture in a separate chapter, the book features easy-to-understand, detailed illustrations, to allow all those involved in inertial navigation to gain a better grasp of GFINS manufacture, including accelerometer setting principles; initial alignment; quaternion-based, attitude resolution algorithms; and accelerometer de-noise methods.

The semiconductor industry is a vital industry for military establishments worldwide, and the control of, or loss of control of, this key industry has enormous strategic implications. This book focuses on the globalization of the strategic semiconductor industry and the security ramifications of this process. It examines in particular the migration of the Taiwanese chip industry to China as part of the globalization of production processes, and the extent to which such a globalization process poses security challenges to the United States, China and Taiwan. Transcending disciplinary boundaries between international political economy, security studies, and the history of science and technology, this multidisciplinary work provides an in-depth understanding of the globalization-security nexus, and disentangles the key policy issues connected to a potential explosive flashpoint in world politics today.

This book provides an introduction to navigation based on global navigation satellite systems, to inertial navigation, and to integrated navigation systems, which can be easily understood, and which is written with clarity.
