主　　题：Micro power generator micro energy transducer high-aspect-ratio MEMS SU-8 processing 

摘      要：This paper presents the design and experimental results of a Micro Power Generator (MPG) which harvests mechanical energy from its environment and converts this energy into useful electrical power. The energy transduction component is mainly a magnet and a resonating spring made using SU-8 molding and MEMS electroplating technologies. We have shown that when the MPG is packaged into an AA battery size container along with a power-management circuit that consists of rectifiers and a capacitor, it is capable of producing ~1.6 V DC when charged for less than 1 min. Our goal is to realize a MPG to function with low input mechanical frequencies while producing enough power for low-power wireless applications.
