Researchers Have Found A Way To Convert Fingertip Sweat To Electricity.

Over the years, methods of generating electricity from various types of waste have been developed, but a new study has found a way to turn sweat into usable energy from our own fingertips.

A group of nanoengineering researchers from the University of California San Diego found that fingertips produce 100 to 1000 times more sweat than any other body part. According to their paper published in the scientific journal Joule, the team conducted a test to generate electricity by attaching a tape-shaped absorbent device to the tip of a finger. The electrodes are loaded with enzymes that generate electricity by inducing a chemical reaction between the lactic acid and oxygen molecules found in sweat. The more you sweat, the more electrical energy is stored in the battery behind the band.

After wearing the wrist device for 10 hours, about 400 millijoules of energy was collected, which is enough to run an electronic wristwatch for 24 hours. According to one of the study’s co-authors, research is being done to generate enough energy to charge a smartphone for daily use.
