Sweat powered smartwatches

Imagine your wearable solution could be charged automatically by using your sweat... Yes you sweat and other energy source!!!

It could be possible in the near future. Engineers at the University of Glasgow have developed a new type of flexible supercapacitor. The device works by coating polyester cellulose cloth in a thin layer of a polymer, which acts as the supercapacitor’s electrode which stores energy, replacing the electrolytes found in conventional batteries with sweat.
