Tunnel Magnetoresistance Sensors with Magnetostrictive Electrodes: Strain Sensors [PDF]
Sensors, 2016 Magnetostrictive tunnel magnetoresistance (TMR) sensors pose a bright perspective in micro- and nano-scale strain sensing technology. The behavior of TMR sensors under mechanical stress as well as their sensitivity to the applied stress depends on the magnetization configuration of magnetic tunnel junctions (MTJ)s with respect to the stress axis. Here,

Graphene–polymer coating for the realization of strain sensors [PDF]
Beilstein Journal of Nanotechnology, 2017 In this work we present a novel route to produce a graphene-based film on a polymer substrate. A transparent graphite colloidal suspension was applied to a slat of poly(methyl methacrylate) (PMMA). The good adhesion to the PMMA surface, combined with the shear stress, allows a uniform and continuous spreading of the graphite nanocrystals, resulting in ...

Mathematical modelling of plasmonic strain sensors [PDF]
Journal of Inverse and Ill-posed Problems, 2020 Abstract We provide a mathematical analysis for a metasurface constructed of plasmonic nanoparticles mounted periodically on the surface of a microcapsule. We derive an effective transmission condition, which exhibits resonances depending on the inter-particle distance. When the microcapsule is deformed, the resonances are shifted.

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 ...
