MUMBAI, India, Feb. 13 -- Intellectual Property India has published a patent application (202541125161 A) filed by Nandha Engineering College, Erode, Tamil Nadu, on Dec. 11, 2025, for 'sensor-based iot walking aid system for visually impaired people.'
Inventor(s) include Dr. T. M Alamelu Manghai; S. Sai Siddhardh; K. Sowmiya; and G. Nandhini.
The application for the patent was published on Feb. 13, under issue no. 07/2026.
According to the abstract released by the Intellectual Property India: "The present invention discloses an Internet of Things {loT)-based smart walking stick specifically designed to aid blind and physically challenged individuals in ensuring safer and more independent navigation. The device integrates multiple electronic modules, including an Arduino UNO microcontroller, an ultrasonic sensor, an MPU6050 accelerometer and gyroscope sensor, a vibration motor, a buzzer, and a Bluetooth (HC-05) communication module. The ultrasonic sensor continuously scans the surrounding area and detects obstacles in the path of the user by measuring distance through ultrasonic waves. When an obstacle is identified within a predetermined threshold distance, the system immediately triggers the vibration motor and buzzer to alert the user through tactile and auditory feedback, allowing the user to change direction and avoid collisions. The MPU6050 module monitors the angular orientation and acceleration of the walking stick. In case of a sudden fall or abnormal tilt indicating that the user might have fallen or lost balance, the sensor data is processed by the Arduino, which then initiates an emergency alert signal. The Bluetooth module (HC- 05) enables wireless communication with a mobile application, allowing transmission of real-time data and notifications to caretakers or family members for quick response and monitoring. The system is powered by a renewable energy setup comprising a solar panel, rechargeable Li-ion battery, and a 5V voltage regulator. This ensures that the stick remains powered even in outdoor conditions without requiring frequent manual . . . . . . .. charging, making the system eco-friendly and self-sustaining. The proposed invention provides a compact, portable, and cost-effective assistive device that enhances safety, independence, and confidence for visually impaired and physically challenged individuals. By combining obstacle detection, fall detection, loT -based connectivity, and renewable energy technology, the smart walking stick offers an advanced, reliable, and socially beneficial solution for real."
