The piezoelectric actuator includes a piezoelectric element and a vibration plate having a bulge. The deformable substrate includes a flexible plate and a communication plate. The flexible plate includes a movable part. Then, the flexible plate and the communication plate are stacked on and coupled with each other to form the deformable substrate. Then, the housing, the piezoelectric actuator and the deformable substrate are sequentially stacked on each other and coupled with each other. A synchronous deformation process is implemented by applying at least one external force to the deformable substrate, so that the flexible plate and the communication plate of the deformable substrate are subjected to a synchronous deformation, and a specified depth between the movable part and the bulge of the vibration plate is defined.

Abstract: A micro-gas pressure driving apparatus includes a miniature gas transportation module and a miniature valve module. The miniature gas transportation module includes a gas inlet plate, a fluid channel plate, a resonance membrane and a piezoelectric actuator. A first chamber is defined between the resonance membrane and the piezoelectric actuator. After the piezoelectric actuator is activated to feed a gas through the gas inlet plate, the gas is transferred to the first chamber through the fluid channel plate and the resonance membrane and then transferred downwardly. Consequently, a pressure gradient is generated to continuously push the gas. The miniature valve module includes a gas collecting plate, a valve membrane and a gas outlet plate. After the gas is transferred from the miniature gas transportation module to the gas-collecting chamber, the gas is transferred in one direction, so that a pressure-collecting operation or a pressure-releasing operation is selectively performed.

Abstract: A fluid transportation device includes a valve supporting module, a first fluid transportation module and a second fluid transportation module. Through the valve supporting module, the first fluid transportation module and the second fluid transportation module may be combined together in a side-by-side arrangement or a vertically-stacked arrangement. The combination of the first fluid transportation module and the second fluid transportation module can increase the flow rate and the pumping head of transporting the fluid. Moreover, the combination of two fluid transportation modules of the present fluid transportation device can be synchronously or asynchronously actuated to increase the flow rate and the pumping head of transporting the fluid. Since the additional coupling mechanism is omitted, the fabricating cost of the present fluid transportation device is largely reduced, and the overall volume of the present fluid transportation device is reduced to comply with the miniaturization requirement.

Abstract: A fluid control device includes a piezoelectric actuator and a deformable substrate. The piezoelectric actuator includes a piezoelectric element and a vibration plate. The piezoelectric element is attached on a first surface of the vibration plate. The piezoelectric element is subjected to deformation in response to an applied voltage. The vibration plate is subjected to a curvy vibration in response to the deformation of the piezoelectric element. A bulge is formed on a second surface of the vibration plate. The deformable substrate includes a flexible plate and a communication plate, which are stacked on each other. Consequently, a synchronously-deformed structure is defined by the flexible plate and the communication plate collaboratively, and there is a specified depth maintained between the flexible plate and the bulge of the vibration plate. The flexible plate includes a movable part corresponding to the bulge of the vibration plate.
