Using Sweat to Power Your Smartphone?

sweat

Our wearables will be able to generate their own energy in the near future, and we are not talking about solar technology here. Researchers in California have come up with a device that can monitor your workout progress and generate power from your perspiration.  Here is how it works:

It works by measuring a chemical called lactate that is naturally present in sweat. The more intense the workout, the more lactate your body produces. The sensor also strips electrons from lactate to generate a small electrical current.

Researchers hope the device will be able to generate enough energy to charge a smartwatch or heart rate monitor in the future.
