摘要： A piezoelectric pump includes a piezoelectric element, a vibrating piece, a valve and a flow guiding member. The vibrating piece has a central zone attached to the piezoelectric element, a peripheral zone, a first recess, a stopper and a position limiting wall both protruding from the first recess, and a through groove disposed between the central zone and the peripheral zone and connected through the first recess. The valve is attached to the peripheral zone and has a non-straight through slit. The flow guiding member is attached to the valve and has a second recess and a channel both recessed in the flow guiding member, and a through hole. The channel is connected through the second recess and the through hole. A projection of the second recess projected on the plane which the valve exists covers the non-straight through slit. An operating method of a piezoelectric pump is further provided.

摘要： 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.
