Tips: How do semiconductor strain gauges differ from ordinary strain gauges?

The core of a semiconductor strain gauge is the piezoresistive effect. Its resistance change mainly originates from the dramatic change in resistivity caused by the distortion of the internal lattice under stress. Therefore, it has an extremely high sensitivity coefficient, typically 50-100 times that of a metal strain gauge. Furthermore, it is small in size, has low mechanical hysteresis, and fast dynamic response, making it ideal for measuring minute strains or for high-frequency dynamic applications (such as biomedical sensing and MEMS pressure sensors). In contrast, ordinary metal strain gauges, based on the strain effect, have resistance changes primarily due to changes in conductor geometry. They have lower sensitivity but excellent linearity, good temperature stability, and are simple in structure, low in cost, and have good toughness. In summary, semiconductor strain gauges are highly sensitive, small-volume, but environmentally sensitive special components, suitable for micro-force measurement and integration into MEMS chips. Metal strain gauges are stable, linear, robust, and durable industrial standard components, suitable for most conventional force and strain measurements.
