IIT Delhi develops a device that can generate electricity through water droplets to power small electronic devices

IIT Delhi researchers have designed and fabricated a device that can generate electricity from water drops, raindrops, water streams, and even from ocean waves using “Triboelectric Effect” and “Electrostatic Induction”. The device is called “Liquid-solid Interface Triboelectric Nanogenerator”. The generated electricity can be stored in batteries for further use.

The new device produces power using Triboelectric Effect and Electrostatic Induction, and further stores the energy in batteries for consumption. It can generate power of only a few Milliwatt (mW), which is sufficient to power small electronic devices like healthcare sensors, digital thermometers, watches, radio frequency transmitters, pedometers.
