Accurate monitoring of soil pressure and temperature is critical for disaster risk management and civil engineering projects. Conventional mechanical or electrical sensors may face limitations in sensitivity, durability, or performance under harsh environmental conditions, reducing reliability in real-time monitoring applications such as landslide detection and infrastructure stability assessment.

This innovation introduces a compact, optical-based soil pressure sensor that utilises fibre Bragg grating technology to measure changes in soil pressure and temperature. The system translates pressure variations into shifts in light wavelength, enabling precise and responsive detection. It has been tested in real soil environments, demonstrating strong sensitivity and operational reliability.
