Researchers Harvest Radio Waves For Power To Eliminate Need For Batteries

Researchers at the University of Bedfordshire have developed a new technique for powering electronic devices.

The system, developed by Prof Ben Allen at the Centre for Wireless Research, uses radio waves as power.

Believed to be a world first, the team claims it could eventually eliminate the need for conventional batteries.

The university has now filed a patent application to secure exclusive rights to the technique.

‘Spare time’

Prof Allen and his team, including David Jazani and Tahima Ajmal, have created a system to use medium wave frequencies to replace batteries in small everyday gadgets like clocks or remote controls.

The new technique uses the “waste” energy of radio waves and has been developed as part of the university’s research into “power harvesting”.

Prof Allen said that as radio waves have energy – like light waves, sound waves or wind waves – then in theory these waves could be used to create power.

“The emerging area of power harvesting technology promises to reduce our reliance on conventional batteries,” he said.
