Physical Interaction Using Wireless Energy Transfer by Ultrasonic from Parametric Loudspeaker

URL

This system enables to manipulate the transfer path of electricity, using the properties of sound waves. Sound waves emitted from parametric loudspeakers are received by a circuit 3cm wide, and are converted to electricity. Because sound waves can be reflected or shielded by objects such as hand and paper, it is easy to manipulate the transfer path of electricity. In our research named VITA, we tested how much people could transfer electricity into these devices by reflecting the sound waves.
