Scientists develop technique capable of generating electricity from vibrations for self-powered devices: The Tribune India

New Delhi, June 26

Scientists have made a simple, cost-effective, biocompatible, and transparent nanogenerator that can generate electricity from all-around vibrations for use in optoelectronics, self-powered devices and other biomedical applications, said on Saturday. government.

The Ministry of Science and Technology, in a statement, said that the search for renewable energy resources with reduced carbon emissions is one of the most pressing challenges due to the growing threat of global warming and the crisis. energetic.

“Some of the unconventional methods of generating electricity include piezoelectric, thermoelectric and electrostatic techniques used in devices such as touch screens, electronic displays, etc.,” the statement said.

Triboelectric nanogenerators (TENGs) use mechanical energy in the form of vibrations found everywhere in different forms to generate electricity, he said.

The energy recovery TENG works on the principle of creating electrostatic charges via instantaneous physical contact of two different materials, followed by the generation of a potential difference when a mismatch is introduced between the two contacting surfaces by through mechanical force, the statement said.

“This mechanism causes electrons to move back and forth between the conductive films coated on the back of the tribo layers. The method used to date to design the TENG uses expensive manufacturing methods such as photolithography or reactive ion etching, as well. as additional processes such as preparation and preparation of electrodes … so on, “he said.
