This leads to a drift of magnetic sensitivity versus mechanical stress, which is caused by piezoresistance
and not by piezo-Hall effect.
nor piezoimpedance would lead to a less hysteretic response due its quantum resistive component that makes exponential relations appear.
 investigated piezoresistance

is the stress component, and the term [[pi].sub.ij] is the component of the piezoresistance
is a passive phenomenon that can be used for sensing of load/pressure through variations in a material's electrical resistance.
This paper deals with the design of pressure sensor with piezoresistance
as the sensing element.
, piezoelectric and resonance frequency are among the sensing principles depending upon the mechanical properties of the devices.
Working by the principle of piezoresistance
, the Tactilus system is a matrix-based tactile surface sensor--essentially an "electronic skin" that can record and interpret pressure distribution and magnitude, and assimilate the collected data into a Windows[R]-based tool kit.The company says the system also boasts of:
Jim Davidson, a researcher at Vanderbilt Univ., Nashville, Tenn., has developed a microelectro-mechanical pressure sensor based on diamond's piezoresistance
By detecting the change in piezoresistance
arising from the stress in the beam, one can construct a miniature accelerometer; such devices are used to trigger air bags and seat belt tensioners in automobiles.
