Abstract
A fluid actuator includes an actuating portion, a piezoelectric unit, a conduction unit, and a levelness regulating portion. The actuating portion includes a first actuating area, a second actuating area, and at least one connecting section between the two actuating areas. The piezoelectric unit includes a first signal area and a second signal area. The two signal areas are provided in the same plane and are isolated from each other by an isolating portion. The piezoelectric unit corresponds in position to the first actuating area of the actuating portion. The conduction unit includes a first electrode and a second electrode. The first signal area of the piezoelectric unit is electrically connected to the first electrode, and the second signal area of the piezoelectric unit to the second electrode. The levelness regulating portion, the piezoelectric unit, and the conduction unit are located on the same side of the actuating portion.
