Micropower Energy Harvesting for Inear Devices
نویسنده
چکیده
This research aims to provide a unique perspective on energy harvesting from ear canal dynamic motion that can be used to power electronic in-ear devices. Two micro-power generators are presented: one of them has a miniature hydro-electromagnetic core and another one is composed of a micro piezo film sheet in shape of a ring. The experimental results will show that 1.2μW and 0.2μW could be successfully harvested by the hydroelectromagnetic and piezoelectric energy harvesting mechanisms respectively. While the scavenged power is currently very low, the mechanical harvesters could be improved and get close to the few milliWatts of mechanical power available from the ear canal dynamic motion.
