Fiber Grating Strain Gauge
The grating strain gauge is a strain sensor based on fiber Bragg grating (FBG) technology. It monitors strain through changes in the FBG spectrum. Its gauge length is benchmarked against resistive strain gauges. It is passive and immune to electromagnetic interference, supports series/parallel sensor networks, has a lifetime >107 cycles (±1500μɛ), and provides high stability without zero drift.
