Low-Cost High-Sensitivity Strain and Temperature Sensing Using Graded-Index Multimode Fibers [PDF]

open access: yes, 2007
We report a low-loss, low-cost high-sensitivity all-fiber strain and temperature sensor based on mode interference in graded-index multimode fibers. Blueshifts with strain and temperature sensitivities of 18.6 pm/microstrain and 58.5 pm/°C have been ...

Nanoparticle Strain Sensor

open access: yesProcedia Engineering, 2011
AbstractStrain sensors have been fabricated by depositing platinum nanoparticles between interdigitated gold electrodes on oxidised silicon substrate. A significant improvement in strain sensitivity is achieved with a gauge factor in excess of 700, which is two orders of magnitude higher than continuous metallic films and five times higher than ...

Tunable MoS2 strain sensor

open access: yesIEEE 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

open access: yesSensors, 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 ...

Investigation of strain measurements in (curved) wide plate specimens using digital image correlation and finite element analysis [PDF]

open access: yes, 2012
Some pipelines face global plastic straining due to the nature of their installation process or harsh environmental conditions during operation. The ability of the girth welds to withstand these plastic strains is often evaluated on the basis of wide ...
