Rotary triboelectric nanogenerators as a wind energy harvester

Abstract

The present scenario of the world reflects the problem of energy crisis it is facing today. Increasing emissions of harmful gases like various byproducts produced by burning fossil fuels and other flue gases are adding to the worsening environmental conditions. Hence, the need of replenishable and non-conventional sources of energy is more than ever before. TENG or triboelectric nanogenerators show great potential and can be at the frontier of renewable energy technologies in the near future. Among the many applications of TENG as a harvester of abundant environmental energy, the Rotary TENG or the R-TENG is a fascinating newly found type of the same. Rotary TENG has the ability of utilizing the energy present in abundant amount in the environment, like wind energy available in the normal environment of living. Wind speed can also be measured with the help of rotary TENG when used as a self powered sensing elements. This growing field of nanotechnology can be further used in the daily lives of people in coming days.
