IEEE Instrumentation & Measurement Magazine, 2020 Molybdenum disulfide (MoS 2 ) is a promising two-dimensional (2D) semiconductor for the realization of electronic devices such as sensors and transducers. Among other mechanical and electronic properties, MoS 2 shows piezoresistive effect due to the strain-induced modulation of its electronic band-gap.

A High-Strength Strain Sensor Based on a Reshaped Micro-Air-Cavity
Sensors, 2020 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 ...

Fiber Bragg Grating Sensors for Pile Jacking Monitoring in Clay Soil
Sensors, 2020 The small deformation of the model pile in a pile jacking test makes its accurate measurement very difficult. Based on the installation method of clamping at both ends, a sensitized miniature fiber Bragg grating (FBG) strain sensor was developed to ...

Metamaterial-based strain sensors [PDF]
2011 Seventh International Conference on Intelligent Sensors, Sensor Networks and Information Processing, 2011 In this paper, two metamaterial-based strain sensors at terahertz frequencies are introduced and simulated using CST Microwave Studio. They exhibit a large shift in the resonance frequency upon stretching or compression. They are very well suitable to monitoring and detecting mechanical deformation of a target structure remotely.
