Scientists might have just come up with the PERFECT way to charge your smart devices in the near-future: with your sweat!
Researchers at the Nanyang Technological University in Singapore have just revealed that they have created a battery that can actually convert two milliliters of sweat into 20 hours; worth of electricity and now your smartwatch is never going to die out.
The battery is apparently only 0.8 square inches and as of right now is worn on a special band that absorbs perspiration and then converts that into power for your smartwatch. As of right now the battery is still just a prototype, but you can see what it looks like in action below!
Something tells me that it might be a little expensive when it is first sold to the public, but in five years from now I can't wait to rock a perspiration battery to charge all of my devices!
