Liquid metal device built with UOW researchers turns movement into power for emergency signals

A liquid metal device developed with University of Wollongong researchers harvests energy from motion, which the university says could let life jackets turn wave movement into an emergency signal.

Why it matters: The device developed with UOW researchers would let emergency signals and wearable sensors run on energy from movement instead of batteries.

The University of Wollongong (UOW) said a liquid metal device that collects energy from movement was developed with its researchers.

According to the university, the harvested energy can power emergency signals and wearable sensors without the need for batteries.

UOW said the technology could allow self-powered life jackets to convert wave motion into an emergency signal.
