Strain-induced magnetoresistance for novel strain sensors

Journal of Applied Physics, 2010
The strain-induced magnetoresistance (MR) has been investigated in detail by simulating the spin-rotation in spin-valve structures. The results show that the strain-induced anisotropy can be utilized to control the relative orientation of the spins in the two adjacently arranged ferromagnetic layers because each layer responds to the external strain ...

Silica microspheres array strain sensor

Optics Letters, 2014
An optical fiber sensor based on arrays of silica microspheres is proposed. The microspheres are produced separately using a fusion splicer and then also connected in series by fusion splicing. Three different sensors are presented, differing by the number of microspheres.

Optical in-plane strain field sensor

Applied Optics, 2002
A whole-field speckle strain sensor is presented. The speckle strain sensor allows the measurement of all three in-plane components of the strain field simultaneously without touching the surface of the sample. The strain fields are extracted from the in-plane motion of defocused laser speckles in a telecentric imaging system.

Piezoresistive Strain Sensors

2009
In contrast to the fixed strain incorporated in logic devices for a fixed or constant improvement in device performance, piezoresistive strain sensors respond to variable strain through a modulation in the device resistance. The underlying physics of performance improvement in logic devices and strain transduction in piezoresistive strain sensors is ...

Chitosan-Polypyrrole Fiber for Strain Sensor

Journal of Nanoscience and Nanotechnology, 2015
A chitosan/polypyrrole composited fiber as bio-compatible materials for artificial muscles is investigated. The chitosan/polypyrrole fiber (CPF) is fabricated by in-situ chemical polymerization of pyrrole monomer solution using FeCl3 as an oxidant. The electrical resistivity of the fiber is changed according to the strain variation applied to the both ...

Graphene/polydimethylsiloxane nanocomposite strain sensor

Review of Scientific Instruments, 2013
The objective of this research is to fabricate graphene nanopowder composites based on polydimethylsiloxane (PDMS) and to characterize the gauge factor of the graphene/PDMS composites for the use of strain sensors. The fabrication of graphene/PDMS composites can be accomplished by simple sonication and micro molding processes.

Flexible platinum nanoparticle strain sensors

2013 Proceedings of the European Solid-State Device Research Conference (ESSDERC), 2013
Using a modified magnetron sputtering technique, platinum nanoparticles having a mean diameter of 4–6 nm have been deposited on flexible polyimide substrates. The polyimide substrates have been previously patterned with gold interdigitated electrodes having an inter-finger distance of 10 μm using conventional photo lithography and the e-gun evaporation
