Japanese Researchers Transmit Power Through Concrete to Tire

Toyohashi University of Technology researchers inductively transmit up to 60 watts through 10 cm of concrete and into full-size automobile tire.

Published: 08-Jul-2012

The Toyohashi University of Technology demonstrated its wireless power transmission technology using electric field coupling with automobile tires and the same concrete as used for public roads.

The demonstration took place at WTP Wireless Technology Park 2012, a trade show on wireless technologies, which runs from July 5 to 6, 2012, in Yokohama, Japan.

A research group led by Takashi Ohira, professor at the university's Department of Electrical and Electronic Information Engineering, has been engaged in the research aimed at using wireless power transmission technologies based on electric field coupling (or inductive coupling) for transmitting power to a running vehicle.
