ENERGY HARVESTING ANALYSIS OF BODY MOTION AS ENERGY SOURCE FOR BIOMEDICAL DEVICES

Abstract eng:
This paper deals with an energy harvesting analysis for a development of an efficient energy harvesting system for the artificial cochlea. The artificial cochlea could be used for a compensation of deafness. This artificial cochlea consists of a MEMS sensor based on banks of mechanical filters, electronics for sensing and electrodes, power supply and packaging. The energy harvesting systems are used for biomedical devices in present time and using of energy harvesting in head area for powering of the artificial cochlea is convenient. There are several types of energy which can be used as a source of energy for this biomedical application. Only 3 types of energy converters are suitable in the head area and the sufficient output power is expected. There are thermal gradient between skin and surroundings, mechanical movement of the head (shocks and vibrations) and bending movement of neck muscles and an artery. The energy harvesting from mechanical movement in head area is analysed in this paper.
