Strain sensor using twisted optical fibers

Optics Letters, 1984
A novel sensor using twisted optical fibers is proposed to detect distributed tensile strain. This sensor converts tensile strain to optical loss. The relation between tensile strain and optical loss is modeled and experimentally confirmed for uniform tensile strain.

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 ...

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 ...

SAW OFC strain sensor

2009 IEEE International Ultrasonics Symposium, 2009
This paper presents results for a 250MHZ orthogonal frequency coded (OFC) surface acoustic wave (SAW) cantilever device on YZ LiNbO 3 . A 1-D model is presented which predicts the variation in the wave velocity with applied strain. A FEM analysis is conducted which verifies the strain on the cantilever and supports the 1-D model predictions.

Mechanochromic polyurethane strain sensor

Applied Physics Letters, 2014
In this Letter, we study the mechanical and optical response of a thermoplastic polyurethane blended with 0.5 wt. % of bis(benzoxazolyl)stilbene dye. The mechanochromic behavior of the material is characterized in a uniaxial stress-relaxation test by simultaneously acquiring the applied force, mechanical deformation, and fluorescence emission. To offer
