Summary, Etc.  

요약The research elaborated in this thesis revolves around the design and application of multiple micro-electromechanical systems (MEMS) that employ piezoelectric and electromagnetic sensors and actuators, which are essential in developing highly efficient sensing systems for applications with limited power resources.The study features the design, simulation, and experimental analysis of a zero-power wireless authentication system. This system utilizes a High-Overtone Bulk Acoustic Resonator (HBAR) as an RFID tag for passive detection of target tampering activity, i.e., temperature elevation for de-soldering followed by mechanical shocks for detaching integrated circuits (ICs) from printed circuit boards (PCBs). The novel system operates at a frequency of 7.56 GHz with an fQ product of more than 1013 and includes an energy harvester that generates a 6V pulse capable of permanently changing the RFID tag's RF spectral properties.Various energy harvesters have been developed using piezoelectric and pyroelectric properties on multiple substrates, including bulk ceramics and bimorph structures, and through thin films. These energy harvesters have been evaluated thoroughly to ascertain their effectiveness in converting extreme thermal and mechanical excitations into electrical energy.Further, the dissertation explores a compact wearable energy harvester that utilizes a non-resonant electromagnetic energy harvesting modality. This device, composed of wound micro-coils and a magnet array suspended in ferrofluid within an acrylic chamber, has been fine-tuned to generate power from low-frequency movements, such as human walking, despite its minimal form factor.In summary, this thesis presents a suite of innovative low-power solutions enabled by MEMS resonators and piezoelectric thin films, suitable for various applications including but not limited to secure wireless authentication of ICs and health monitoring using wearables.
