Could your sweat one day charge your fitness tracker?
Peer-reviewed: This work was reviewed and scrutinised by relevant independent experts.
Your fitness tracker could one day be powered by your own sweat, according to Australian researchers who have developed tiny, sweat-powered nanogenerators that can be stored in clothing. The team say their hydroelectric nanogenerators, which they tested on woollen cloth, generate enough energy from the evaporation of sweat to power small electronic devices. This technology could one day lead to wearable fitness trackers that don't require charging, the researchers say.
