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.
