Design of Micro Power Self-Generation Device

Abstract:

Power supply for micro-system such as wireless sensor network node (WSNN) is an open and interest issue. In this paper, the principle of power self-generation device based on mechanical vibration transformation is introduced, which absorb the energy of mechanical vibration and transform to pressure on piezoelectric materials to produce micro-current, and a mechanical frequency-adjustable vibration absorber based micro electricity self-generation device is designed.
