Wirelessly transfer data & energy bidirectionally.

UWP - An UltraPower Technology

Our technology integrates ultrasound energy and piezoelectric materials to recharge batteries and/or deliver power remotely. UWP was developed by UltraPower, Inc. and its subsidiary, Piezo Energy Technologies, LLC. (PET), the first companies to recharge batteries remotely using ultrasound.

The Technology

Batteries are frequently embedded within a dense micro-component package, or electrically-conducting media, where electromagnetic wireless powering is either limited or impossible. UPD uses a pitch-catch technique to wirelessly transmit power through various materials, dramatically expanding the design potential for devices powered via wireless charging.
