We demonstrate a high-strength strain sensor based on a micro-air-cavity reshaped through repeating arc discharge. The strain sensor has a micro-scale cavity, approximate plane reflection, and large wall thickness, contributing to a broad free spectrum range similar to 36 nm at 1555 nm, high fringe contrast similar to 38 dB, and super-high mechanical robustness, respectively. A sensitivity of similar to 2.39 pm/mu epsilon and a large measurement range of 0 to 9800 mu epsilon are achieved for this strain sensor. The strain sensor has a high strength, e.g., the tensile strain applied the sensor is up to 10,000 mu epsilon until the tested the single-mode fiber is broken into two sections. In addition, it exhibited low thermal sensitivity of less than 1.0 pm/degrees C reducing the cross-sensitivity between tensile strain and temperature. |
