Studies on Temperature and Strain Sensitivities of a Few-mode Critical Wavelength Fiber Optic Sensor [PDF]
, 2018 This paper studied the relationship between the temperature/strain wavelength sensitivity of a fiber optic in-line Mach-Zehnder Interferometer (MZI) sensor and the wavelength separation of the measured wavelength to the critical wavelength (CWL) in a CWL-

Compliant Mechanism-Based Sensor for Large Strain Measurements Employing Fiber Optics
Sensors, 2022 We propose a sensor design for measurement of large strains where direct application of a fiber optic strain gauge is impossible due to the stiffness mismatch between the optical fiber and the structure under test. The sensor design is based on a rhombus

Piezotronic effect in AlGaN/AlN/GaN heterojunction nanowires used as a flexible strain sensor
Beilstein Journal of Nanotechnology, 2020 1D semiconductor nanowires (NWs) have been extensively studied in recent years due to the predominant mechanical flexibility caused by a large surface-to-volume ratio and unique electrical and optical properties induced by the 1D quantum confinement ...
