An AA-Sized Vibration-Based Microgenerator for Wireless Sensors

摘要

This paper deals with the vibration-to-electrical transducer that has an M-size form factor and generates a DC voltage that can power off-the-shelf integrated circuits. Vibration-powered wireless sensors obtain power from machine vibrations, human movement, or other forms of motion. The feasibility of incorporating micro power transducers (MPTs) with a voltage multiplier and rectifier to make a micro power generator (MPG) is demonstrated, that has the same size and shape as an AA battery. The AA-sized module includes a voltage multiplier and a large capacitor to produce the DC output
