DTN News - SPECIAL REPORT: Berkeley Lab Scientists Generate Electricity From Viruses
(NSI News Source Info) TORONTO, Canada - July 7, 2012: The scientists tested their approach by creating a generator that produces enough current to operate a small liquid-crystal display. It works by tapping a finger on a postage stamp-sized electrode coated with specially engineered viruses. The viruses convert the force of the tap into an electric charge.
Their generator is the first to produce electricity by harnessing the piezoelectric properties of a biological material. Piezoelectricity is the accumulation of a charge in a solid in response to mechanical stress.
