Abstract
There is provided a piezoelectric actuator device including a piezoelectric actuator which includes a plurality of piezoelectric elements, each of which has a piezoelectric layer sandwiched between two types of electrodes; and a plurality of driver ICs which drive the piezoelectric elements, wherein a part of the piezoelectric elements are connected to the plurality of driver ICs.
Claims13
A piezoelectric actuator device, comprising:
- a piezoelectric actuator which includes a plurality of piezoelectric elements, each of the piezoelectric elements having two types of electrodes and a piezoelectric layer sandwiched between the two types of electrodes;
- and
- a plurality of driver ICs;
- and
- a plurality of wiring lines, each of which connects one of the driver ICs to one of the piezoelectric elements;
- wherein each of the piezoelectric elements is connected to at least one of the driver ICs via one of the plurality of wiring lines, and is driven by the respective driver IC by changing a voltage applied between the two types of electrodes of the respective piezoelectric element;
- wherein each piezoelectric element in a group of the piezoelectric elements is connected to at least two of the plurality of driver ICs.
