摘要： An actuating device includes an actuator and a stationary portion. The actuator has at least one driving portion. The stationary portion is provided at an arbitrary position along the actuator such that the driving portion forms a first driving portion and a second driving portion. The first driving portion and the second driving portion can be provided with the same actuating ability or with different actuating abilities respectively by adjusting the position of the stationary portion.

摘要： An 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.

摘要： A fluid driving device includes a vibration unit, a signal transmission layer, a piezoelectric element, and a plane unit. The signal transmission layer includes a first conductive zone and a second conductive zone. The piezoelectric element includes a first electrode and a second electrode electrically isolated from each other. The first electrode of the piezoelectric element is electrically connected to the first conductive zone of the signal transmission layer, and the second electrode of the piezoelectric element is electrically connected to the second conductive zone of the signal transmission layer. The plane unit has at least one hole. The signal transmission layer, the piezoelectric element, and the plane unit are located at one side of the vibration unit and sequentially stacked with each other.
