Polymer microresonator strain sensors
IEEE Photonics Technology Letters, 2005A new class of fiber-based polymer microresonator strain sensors is analyzed and demonstrated. The flexible sensors are fabricated using a liftoff process and are based on the distortion of the microring by strain and the subsequent shift of the resonant wavelength. For the demonstration, a controlled strain was achieved by flexing the sensor.

We examine a new class of sensitive and compact passive strain sensors that utilize a pair of narrow bent beams with an apex at their mid-points. The narrow beams amplify and transform deformations caused by residual stress into opposing displacements of the apices, where vernier scales are positioned to quantify the deformation.

Organic semiconductor strain sensors
63rd Device Research Conference Digest, 2005. DRC '05., 2005In this paper, the authors report the first strain sensors using an organic semiconductor as the active element. The authors have used a doped organic semiconductor as the active element for low Young's modulus strain sensors. The sensor cross-section is shown.

Magnetostrictive Dynamic Strain Sensor
SAE Technical Paper Series, 2001<div class="htmlview paragraph">The Magnetostrictive Dynamic Strain Sensor is a permanent-magnet constant-flux excitation sensor and thus requires no other electrical excitation or power source. It does not require any signal conditioning. Since it is a constant-flux dynamic sensor, it does not generate any offset voltage and it does not exhibit ...

Polycrystalline silicon strain sensors
Sensors and Actuators, 1985Abstract A new theoretical model for piezoresistance in both n- and p-type polycrystalline silicon is described. This model considers piezoresistance in both the grains and in the Schottky-type barrier regions around the grain boundaries. Transport across the grain boundary is assumed to be dominated by thermionic emission. The effect of strain is to

A drive line vibration sensor includes a housing having a strain gage attached to the drive line component, and an actuator disposed within the housing. In operation, the actuator exerts a force upon the strain gage proportional to acceleration experienced by the actuator.
