An all-optical fiber curvature sensor is proposed, which is composed of a polydimethylsiloxane elastic material encapsulated all-optical fiber Mach-Zehnder interferometer, and its bending characteristics are demonstrated. Our experimental results show that the output spectrum of the sensor is sensitive to the curvature of the bend angle with a result of interferent dip wavelength drift with it. The curvature sensitivity of the sensor presents 205.36 nm/cm(-1) with 98.27% linearity in the curvature range from 0.03 to 0.08 cm(-1). The temperature sensitivity is 0.1235 nm/degrees C in 35 degrees C to 105 degrees C range. This sensor structure also has the advantages of small size, low cost, and easy fabrication, which means it has potential applications in robots, artificial intelligence, aerospace, and so on.
