Modelling of Wireless Energy Harvester

Energy is an important issue for the development of human civilization, but the problem of exhaustion with-in decades of the principal fossil source of energy applied for energy consumption of almost whole world must be confronted. Design and simulation of MEMS based Electromagnetic device which capable of converting waste energy such as vibration to electrical energy. For most wireless applications, the ambient vibration is generally at low frequencies and traditional scavenging techniques cannot generate enough energy for proper operation. The reported generator up-converts low-frequency environmental vibrations to a higher frequency through a mechanical frequency up-converter using a magnet, and hence provides more efficient energy conversion at low frequencies. Power is generated by means of EM induction using a magnet and coils on the top of resonating cantilever beams.
