Temperature compensation of piezoresistive pressure sensors

Sensors and Actuators A: Physical, 1992
Abstract A major problem associated with piezoresistive pressure sensors is their cross sensitivity to temperature. The influence of temperature is manifested as a change in the span and offset of the sensor output. Moreover, in batch fabrication, minor process variations change the temperature characteristics for individual units.

Modeling of Micromachined Piezoresistive Pressure Sensors

IETE Journal of Research, 2006
This paper presents a model for piezoresistive pressure sensor. The model assumes a plane stress condition and it accounts for the finite stiffness of the step up support, which is represented by elastically restrained boundary condition. Variation of stress due to thermal mismatch between silicon and dielectrics and change in piezoresistance due to ...

A High Sensitivity Piezoresistive Pressure Sensor

First International Conference on Integration and Commercialization of Micro and Nanosystems, Parts A and B, 2007
In the current investigation, the piezoresistive effect in a van der Pauw (VDP) stress sensor subjected to biaxial stress was considered. The VDP resistance equations were combined with the silicon piezoresistivity equations to yield relations for the change in resistance of a VDP sensor in terms of the applied state of stress.
