The piezoelectric ceramic positioning system is considered to be the high-precision positioning device in the electrochemical
imaging detector, which can achieve the nanometer scale displacement resolution. This paper describes in detail the
principle of output displacement measuring for piezoelectric ceramic by the resistance strain gauge. In addition, by employing
the self-built drive circuit and the displacement detecting circuit, integrated piezoelectric ceramic resistance strain gauge sensor
has been investigated under both open-loop and closed-loop control, respectively. Under the closed-loop control testing, with a
classic PID algorithmwas applied. Test results show that, the piezoelectric ceramics in open-loop control exhibits disadvantages
of serious non-linearity, hysteresis and creep resistance. However, these issues have been resolved under closed-loop control.
