IIT (ISM) Dhanbad researchers have patented a temperature-independent optical tilt sensor that measures structural inclination in two directions using Fiber Bragg Grating technology. The sensor uses a glass-fibre rectangular arm with a suspended spherical pendulum enclosed in a compact box, designed to reduce errors from temperature changes.
Associate Professor Dr Amitesh Kumar and research scholar Randhir Kumar Sah are the inventors. Their patent was filed on February 10, 2025, for the 'Temperature Independent 2-D Optical Tilt Sensor'.
The lightweight, electromagnetic-interference-resistant sensor suits harsh environments and requires low maintenance. Applications include structural health monitoring of bridges, industrial automation, robotics, aerospace, medical equipment, and geotechnical systems.
Indian Opinion Analysis
The patent grants IIT Dhanbad exclusive rights for a fixed term, typically 20 years from filing, after which the technology enters the public domain. For infrastructure-monitoring sensors, the key challenge is cost: FBG-based sensors remain expensive compared to MEMS tilt sensors, which already dominate the commercial market at Rs 500-2,000 per unit. The institute must now find a licensee willing to manufacture at scale for the sensor to reach actual bridges or industrial plants. The real test will come when the first field deployment on a National Highway Authority bridge or a metro rail project quantifies performance against existing alternatives.
