Ultrasound powers triboelectric device

“An ultrasound probe delivers mechanical energy through skin and liquids, enabling its harvest by a thin implantable vibrating triboelectric generator. As it absorbs the ultrasound waves, the generator yields an electric current that is substantial enough to power cardiac implants and other medical devices,” so report researchers at Sungkyunkwan University in Seoul, South Korea.    MORE
