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.
