New Delhi: A team of scientists has fabricated a simple, cost-effective, bio-compatible, nanogenerator that can generate electricity from mere vibrations for use in optoelectronics, self-powered devices, and other biomedical applications. Search for renewable energy resources with reduced carbon emissions is one of the most urgent challenges due to the increasing threat of global warming and the energy crisis. Among other things, mere vibrations are being harnessed to produce electricity. Triboelectric nanogenerators (TENG) are new energy devices that generate electricity from vibrations. They work on the principle of the creation of electrostatic charges via instantaneous physical contact of two dissimilar materials…
