Have you ever thought about using your sweat to monitor your workout and recharge your mobile device? A research team led by Joseph Wang, a distinguished professor of nanoengineering at the University of California, has developed an innovative biosensor that can track exercise progress and produce an electrical charge for smartphones and other electronic devices.
The sensor, mounted in a temporary tattoo, contains an enzyme that produces an electrical current to measure sweat lactate levels during exercise. The sweat is then used to generate power via the principles of electrons.
The advantage of such “biobatteries” over traditional batteries is they recharge more quickly, use renewable energy (your sweat) and don’t explode or leak toxic chemicals, according to the researchers.
