Sweat Powered BioFuel

A new wearable sensor turns the sweat of your finger or touch into s source of power.

We're not exactly talking about Ironman's arc reactor but they were able to generate enough power in a 10-hour sleep to charge a watch for a day. Then again tape this stuff on some of these Fortnite sweats - you may actually be in the arc reactor conversation.

"What’s special about this sweat-fueled device is that it generates power even while the wearer is asleep or sitting still. This is potentially a big deal for the field of wearables because researchers have now figured out how to harness the energy that can be extracted from human sweat even when a person is not moving."
