Mit Wireless Energy Transfer. Wpt is useful to power electrical devices where are inconvenient or not possible as is the case of body embedded sensors actuators and communication devices. That kind of energy loss poses a significant roadblock to the commercial viability of these technologies as energy aint free.
Spring 07 senior design projecta side project to the wireless ipod charger. Energy is transmitted through electromagnetic waves over long distances using emrods proprietary beam shaping metamaterials and rectenna technology. Wireless power transfer technology reduces the.
Wireless transfer of 60w of power over 2 meter distances.
A group from mit led by prof. Mit researchers transferred about 45 of the energy input while intels recent project showed an 80 transfer. With this increased attention proof of concept experiments have begun which are now leading to product development worldwide. The efficiency is pretty low but we needed to test our project first on an led.
