Researchers at IIT Delhi have developed a device that produces electricity from raindrops

NEW DELHI: Researchers at IIT Delhi have invented a device called the “Liquid-solid Interface Triboelectric Nanogenerator,” which uses the “Triboelectric Effect” and “Electrostatic Induction” to generate energy from water drops, rainfall, water streams, and even the ocean. The device’s structure is basic, according to IIT Delhi, and it consists of nanocomposite polymers and contact electrodes. The gadget can generate a few milliwatts (mw), enough to charge small electric devices such watches, digital thermometers, radio frequency transmitters, healthcare sensors, and pedometers.

The current gadget will be able to create more electricity when compared to other effects such as the piezoelectric effect.

When a specific amount of mechanical stress is applied, the piezoelectric effect can generate an electric charge. However, IIT Delhi researchers have been experimenting with the triboelectric effect to create electricity from wasteful mechanical vibration.

Prof Khare and Dr Huidrom Hemojit Singh illustrated how the gadget generates energy when water rolls over its surface in a recent paper titled “Advanced Material’s Interfaces.”

The Ministry of Science and Technology, as well as the Ministry of Electronics and Information Technology, have reportedly sponsored the research under the NNetRA, according to the Economic Times.

Furthermore, the IIT Delhi study team investigated the mechanism through which the device creates electricity when a water drop makes contact with a solid surface. According to ANI, the research team discovered that saline water drops produce more electricity while investigating the mechanism.
