A scientific team from the University of California, San Diego, has invented an energy-storing patch.
Sweat plays a crucial role in energy production. That's why fingertips producing the most moisture is where the energy-storing patch is attached. The patch looks like a thin strip covered with carbon foam preventing your skin from drying out. Once the patch meets the body, oxygen and lactate molecules react and generate electricity.
You can even use the patch whilst you sleep. After ten hours of sleep, each finger of the volunteer generated about 400 millijoules of energy. This amount of energy is enough to power a smartwatch for nearly a day. It is not the only development by the team. They have also created a piezoelectric finger generator that triggers when touched. As a result, it will be feasible to generate energy even while you are working at your computer.
