Vibration-driven Micro Generator

Abstract

The study on vibration-driven micro generators was discussed. Typical vibrations around us were shown and some ideas of micro generators based on the vibrations were introduced. Advantages and disadvantages of electrostatic induction generators and electromagnetic generators were described. After that, the difference between electret generator and piezoelectric generator, although these two categories are belonging to electrostatic induction generators, were discussed. Finally some examples of electrostatic induction micro generators were shown.
