Design of Kinetic Energy Harvester for Body-worn Sensors and Personal Electric Devices

신체의 움직임을 통한 센서 및 전기장치 전원공급용 에너지 하베스터 설계

This paper presents an electromagnetic kinetic energy harvester which is suitable for supplying power for body-worn sensors and personal electric devices. Human motions are investigated by measuring the acceleration signal at each points of the body during walking and running. The dynamic characteristics of the harvester can be calculated from the transfer function of the system. The transduction factor can be calculated from the electromagnetic field analysis by Maxwell software. The prototype of the harvester is designed and manufactured. The theoretical power characteristics are compared with the experiment results.
