Recent technological advancements have brought seemingly unimaginable happenings to life. For example, do you know your body generates electricity enough to charge devices? A group of researchers have improved the system to create electric charge via the human finger (learn more).
Electricity is universal even in the human body (learn more). Typically, our cells are specialised to conduct electric currents. Electricity enables the nervous system to function by sending signals throughout the body and to the brain.
Our bodies have elements like sodium, potassium, calcium and magnesium, have a specific electric charge. Almost all our cells can use these charged elements called ions to generate electricity.
While basic science explains electricity in the body, researchers have discovered a way to utilise the electric charge for external devices.
The technology involves the use of a finger pad that charges your phones and watches through your sweat. Imbedded in the pad are carbon electrodes primed with enzymes. These trigger a reaction between lactase and oxygen in sweat, thereby producing an electric charge.
For instance, 10 hours of sleep can produce enough to power a watch for a full day. The pad is flat and transparent except for the electrode surface; it sticks to the fingertip when worn and doesn’t require any muscular movement to produce charge.
The scientists who developed this innovation are optimistic that someday the technology will power mobile phones, smart glasses or fitness trackers.
