Researchers have developed a small device made of gold and silicon that fits into the body and can generate electricity when the finger is flexed or other simple movements are performed.MirrorFebruary 12 news.
The device, which is 1.5 cm long, is made from two thin layers of gold with a layer of silicon in between. Flexing your finger creates friction between the gold layers, causing electrons to move back and forth and generate electricity.
In tests conducted by the research team, the device generated a maximum voltage of 124 V and simultaneously lit 48 red LEDs, which can be used to charge electronic devices.
"No one likes to be tied to a power outlet or carry around a spare charger. The human body is a rich source of energy. We thought, why not take advantage of it to generate our own electricity?", said researcher Qiaoqiang Gan at the University at Buffalo.
The researchers are also developing a portable battery to store the electricity generated by the device. They envision the system serving as a power source for wearable electronics and a variety of other devices.
