California, July 15: Researchers at the University of California in San Diego created a thin, flexible piece of foam made out of carbon nanotube material and a hydrogel that is to be worn on the fingertip. It generates a small amount of electricity from the sweat produced by the fingertip, which is a 24-hour factory of perspiration. There are more than a thousand sweat glands on our fingertip. The size of the device is about one square centimeter. The device is called a biofuel cell (BFC) and is charged by lactate, a dissolved compound in sweat. A series of electrochemical reactions happen when the lactate comes in contact with the cell. tricity.
It produces 300 millijoules (mJ) of energy per square centimeter. The device does not require any physical input to generate energy, thereby making it more convenient and accessible for every person. It has also certain additional features like if the finger is pressed while typing, texting, playing the piano, or tapping in Morse code, it creates extra electricity.
