What is Piezoresistive effect?
The change in a material's electrical resistivity under mechanical stress. It is especially large in silicon and is used in semiconductor pressure sensors and similar devices.
Field: MEMS and sensors
Piezoresistive effect in the explanations
Stress alters silicon's band structure, changing its resistivity tens of times more than a metal strain gauge (the piezoresistive effect).
