MUMBAI, India, July 13 -- Intellectual Property India has published a patent application (202611021573 A) filed by Dr. Gaurav Kumar Chaudhary; Mr. Devansh Mishra; and Mr. Ahmad Rushan on February 24, 2026, for A Reusable Triboelectric Self-Charging Multi-Layer Filtration Mask Using Natural Textile Materials.
Inventors include Dr. Gaurav Kumar Chaudhary; Mr. Devansh Mishra; and Mr. Ahmad Rushan.
The application for the patent was published on July 10, 2026, under issue no. 28/2026.
Abstract: The present invention relates to a reusable, eco-friendly face mask employing a multilayer architecture of natural textile materials to achieve high-efficiency particulate filtration. The mask integrates silk and wool triboelectric layers that generate and sustain electrostatic charge during breathing, thereby enhancing capture of sub-micron aerosols without synthetic polymers or external power. Moisture-buffering inner layers and seam-sealing inserts preserve filtration performance during prolonged use. The invention provides a sustainable alternative to disposable N95 respirators suitable for decentralized manufacturing and extended community use.
