UMass researchers develop sweat-powered electricity

A team of researchers has created a sweat-powered biofilm that sticks onto the skin like a bandage, converting the wearer’s perspiration into electricity in a process that could be harnessed for wearable devices.

The design from the University of Massachusetts (UMass) Amherst uses the process of a person’s sweat evaporating to generate energy, with the biofilm made of bacteria that harvests the energy from evaporation and converts it into electricity.

The design has been heralded by the team as providing a means of accessing a previously untapped and significant source of energy.

“This is a very exciting technology,” said Xiaomeng Liu, lead author of the study. “It is totally green energy.”
