Design and Development Of Human Powered Generator for Portable Electronic Equipment

Abstract

A system is proposed to design a vibration based micro generator that uses a mass spring system attached with a coil to convert mechanical energy to electrical energy by faraday’s law of induction. The goal of our research is to create a minimum sized electric power generator, which is capable of producing enough voltage to operate cellphone and other low power devices. Thus far we want to produce a 3.6-volt DC with very low frequencies and low vibration amplitude such as 3 to 5 Hz frequency and 2 to 5mm vibration amplitude. A comparison of performance between theoretical and practical generated voltage is also shown. Other applications for this generator are heartpacers, power source for VLSI system design, military survival systems and robotics systems etc. Now with growing interests and technologies we believe that our human powered generator will find many other applications in future.
