The researchers at the Indian Institute of Technology (IIT) Delhi have designed a device that can generate electricity from water drops, raindrops, water streams, and even from ocean waves using the 'triboelectric effect' and 'electrostatic induction'. The electricity generated by the device called 'Liquid-solid Interface Triboelectric Nanogenerator' can be stored in batteries for further use.
