Remote control requires no battery

NEC and Soundpower have come together to develop a remote control prototype that does not require any battery to run at all, where it will target home electric appliances when commercialized. This remote control was made possible thanks to a vibration-based power generation device developed by Soundpower, coupled with NEC Electronics’ microcomputer supporting RF remote controls which require radio waves with a frequency band ranging from several tens of MHz to several GHz in order to transmit and receive data. All of that will work in tandem with a power supply control technology which drives electronic circuits thanks to a small amount of electricity. Guess couch potatoes would be pretty happy with this, eh?
