MUMBAI, India, Feb. 27 -- Intellectual Property India has published a patent application (202611005755 A) filed by Gurwinder Singh, Jaipur, Rajasthan, on Jan. 20, for 'frostbite prevention smart insole.'
Inventor(s) include Gurwinder Singh.
The application for the patent was published on Feb. 27, under issue no. 09/2026.
According to the abstract released by the Intellectual Property India: "A frostbite prevention smart insole system monitors foot temperature and moisture within footwear to provide automatic haptic alerts during extreme cold and wet conditions. The ultra-thin insole integrates a DS18B20 temperature sensor, BC547 transistor-based wetness detector, ATtiny85 microcontroller, 10 mm coin vibration motor, and CR2032 battery, all positioned in the arch region for comfort with only 2-3 mm added thickness. Operating in deep sleep 99.9% of the time, the system wakes every 30 minutes for 1.8-second measurements, activating repeating 1-second vibration pulses when temperature drops below 2 C (Adjustable during programming) and/or wetness is detected, ensuring early warning before tissue damage without user intervention or smartphone connectivity. This autonomous, long-life (10-12 months) design prevents frostbite for mountaineers, military personnel, and winter workers through dual-sensor closed-loop haptic feedback while preserving natural gait biomechanics."
