Piezoelectric actuators are widely used as fine-motion actuators for  positioning devices. Current pulse driving reduces displacement hysteresis,  and the drive circuit provides current pulses considered constant charge  pulses to the piezoelectric actuator. The circuit for devices with multiple  degrees of freedom using multiple piezoelectric actuators should be simple.  Matrix circuits are used to drive liquid crystal displays to reduce the  number of drive-circuit control signals and components. A group of 2 × 2 piezoelectric actuators was driven alternately using a 4-switch matrix  circuit, and two field effect transistors were used as a fast matrix circuit  switch. Piezoelectric actuator drive performance was studied in the case of  using the current pulse circuit and the matrix circuit. When the matrix  circuit drove actuators performing as capacitive loads, switching device  junction capacitors adversely affected drive performance.
