  • Strain Gauge

    Strain gauge sensors are widely applied to measure the piezoelectric displacement. In this chapter, one piezoelectric actuator (PZT stack) is used to illustrate the measuring principle of strain gauge sensors. Two resistive films are bonded to the PZT stack, as shown in Figure 6.5.The length change of the piezoelectric stack alters the resistance of the strain gauge.
