Recent trends in energy management of wireless wearable bio sensor design

Mobile healthcare systems have great potential for continuous monitoring. These devices are often battery operated. Thus energy management in these wearable, wireless devices is a big challenge for longer durations. In this paper a systematic review of various techniques suggested in literature for energy efficiency and management in such wireless devices is presented. Various research efforts made to optimize the power of wearable, wireless devices at system level, algorithm level and circuit level have been presented. It is followed by energy harvesting technology and wireless power transfer technology useful for energy management in wearable devices.
