MUMBAI, India, May 29 -- Intellectual Property India has published a patent application (202621040934 A) filed by Atal Bihari Vajpayee Indian Institute Of Information Technology And Management, Gwalior, Madhya Pradesh, on March 31, for 'hybrid nanocomposite-based triboelectric nanogenerator for energy harvesting.'
Inventor(s) include Srivastava, Anurag; Yadav, Prakash; and Tyagi, Vandana.
The application for the patent was published on May 29, under issue no. 22/2026.
According to the abstract released by the Intellectual Property India: "The present disclosure provides a hybrid nanocomposite-based triboelectric nanogenerator system that includes a first electrode layer, a tribonegative layer coupled to the first electrode layer, a second electrode layer, and a tribopositive layer comprising a metal oxide-doped carbon-based nanocomposite coupled to the second electrode layer. The tribonegative layer and the tribopositive layer are configured in a contact-separation arrangement to generate an electrical charge upon mechanical contact and separation between the tribonegative layer and the tribopositive layer. The metal oxide-doped carbon-based nanocomposite comprises zinc oxide-doped graphite, and the tribonegative layer comprises polytetrafluoroethylene polymer. The system further includes an encapsulation layer surrounding the electrode layers and triboelectric layers, a nanocomposite material for triboelectric energy harvesting and a method of fabricating the triboelectric nanogenerator are also provided."
