Tattoo That Can Convert Sweat Into Electricity Revealed

Scientists at the University of California San Diego have found a way to transform sweat into electricity – a temporary tattoo-like sensor that monitors lactate, a substance which is present in sweat and the levels get more concentrated as the amount of activity increases.

The sensor uses an enzyme to collect electrons from lactate and convert it into a modest amount of electricity. It is said that the highest amount of energy which has been produced by a single person during the test ended up at 70 microWatts per square centimeter of skin, but there is further research being made to increase the efficiency of system so that it can be used to power small gadgets like watches.
