from a small metallic tab that, when attached to the body, is capable of generating electricity from bending a finger and other simple movements.
That's the idea behind a collaborative research project led by University at Buffalo and Institute of Semiconductors (IoP) at Chinese Academy of Science (CAS). The tab, a triboelectric nanogenerator, is described in a study published online Jan. 31 in the journal Nano Energy.
"No one likes being tethered to a power outlet or lugging around a portable charger. The human body is an abundant source of energy. We thought: 'Why not harness it to produce our own power?'" says lead author Qiaoqiang Gan, Ph.D., associate professor of electrical engineering in UB's School of Engineering and Applied Sciences.
Triboelectric charging occurs when certain materials become electrically charged after coming into contact with a different material. Most everyday static electricity is triboelectric.
