This paper presents the preliminary design and experimental results of a standard AA size vibration-induced micro energy transducer which is integrated with a power-management circuit. The generator is a spring mass system which uses laser-micromachined copper springs to convert mechanical energy into electrical power by Faraday's Law of Induction. A power-management circuit is used to step up the AC output and act as a reservoir to store the electrical energy generated. Our goal is for the generator to provide 3V DC output with low input mechanical frequencies, and to produce enough power for low-power wireless applications. Potential applications for this micro power generator to serve as a power supply for infrared transmission and radio frequency transmission was proved to be possible with input frequencies below lOOHz and amplitudes be 250microns..

This paper presents the preliminary design and experimental results of a standard AA size vibration-induced micro energy transducer which is integrated with a -power-management circuit. The transducer is a spring mass system which uses SU-8 molding and MEMS electroplating technologies fabricated copper springs to convert mechanical energy into electrical power by Faraday's Law of Induction. 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 -1.6V DC when charged for less than Imin. Potential applications for this micro power generator to serve as a power supply for a wireless temperature sensing system was proved to be possible with input frequencies at about IOOHz and amplitudes be approximately 250microns.
