Researchers have developed a metallic tab that, when attached to your human body, is capable of producing electricity from bending a finger along with other straightforward moves.
According to a research project led by the University at Buffalo, New York, and Institute of Semiconductors (IoP) in the Chinese Academy of Science (CAS), the tab — a triboelectric nanogenerator — may convert mechanical energy into electric energy for electronic devices.
“The human body is an abundant supply of energy. We thought: ‘Why not harness it to produce our own electricity?'” Said lead author Qiaoqiang Gan, associate professor at the University at Buffalo.
Triboelectric charging occurs when certain materials become electrically charged after coming into contact with a different substance. Most everyday static electricity is triboelectric.
The tab consists of two thin layers of stone, with polydimethylsiloxane (also called PDMS — a silicon-based polymer used in contact lenses, Silly Putty and other products) sandwiched between.
1 coating of gold is elongated, causing it to crumple upon release and make what seems like a miniature mountain range. When that force is reapplied, for instance, in the finger bending, then the motion leads to friction between the golden layers and PDMS.
The more friction, the greater the quantity of power is produced,” said Yun Xu, professor at the IoP.
That is not enough to quickly control a smartphone but it lit 48 red LED lights concurrently.
The group is planning to utilize larger pieces of gold, which when elongated and folded together are anticipated to provide more power.
The researchers are also working on developing a mobile battery to store energy made by the tab.
They picture the system serving as a power source for various wearable and self-powered electronics devices.
