Simulation of Electromagnetic Generator as Biomechanical Energy Harvester

Portable electronic devices are dependent on batteries as the ultimate source of power. Irrefutably, only have a limited operating period they need to be regularly replaced or recharged. In many situations, power grid infrastructure is not easily accessible recharge and recharging duration also convenient for user wait. Enhancement reliable system by preventing interruptions in remote areas essential. Similarly, modern medical instruments implant reliable, almost maintenance-free ensure able operate all situations without any interruptions. this paper, small-sized electromagnetic generator was designed produce higher utilizing knee angle transition involved during walking phase input rotary force. The proposed design investigated through COMSOL Multiphysics simulation. achieved output RMS range 3.31 W 14.95 based RPM between 360 800 RPM.
