Flexible FBG Strain Sensor

Flexible fiber optic grating strain sensors can be attached to flat or curved surfaces, and a single optical fiber can be connected in series with multiple sensors; Silicone strain gauges are flame retardant, self extinguishing, and resistant to high and low temperatures. They are only 25 × 5.5 × 1.3mm in size and are suitable for limited spaces. The material and size can be customized.

Metal FBG Strain Sensor

The metal fiber optic grating strain sensor is based on linear strain measurement of grating wavelength drift, and is fixed to the surface of the measured part by adhesive. It can be connected in series at a single point, multiple points, or customized to form a network of sensors.

Fiber Bragg Grating Embedded Strain Sensor

The FBG embedded strain sensor is a specialised measurement device developed for materials such as concrete, reinforced concrete, and steel structures. Its core function is to capture strain variations inside the material. By continuously monitoring these minute deformations, it enables in-depth analysis of the structural stress state, timely detection of potential risks, and facilitates fault warning and condition assessment.
