Abstract: A gas transportation device includes a gas outlet cover, at least one flow-guiding pedestal, a primary gas pump, a secondary gas pump and an adhesive film. The gas outlet cover includes a gas outlet nozzle and a gas outlet cavity. Each flow-guiding pedestal includes a main plate, a protruding frame and a chamber frame. The main plate includes a recess and a communicating aperture. The primary gas pump is disposed in the protruding frame, and the secondary gas pump is disposed in the chamber frame. The adhesive film has a hollow structure, is disposed between the primary gas pump and the flow-guiding pedestal and defines a convergence chamber. Consequently, the gas is introduced into the recess, transported to the primary gas pump through the communicating apertures and the convergence chamber, transported to the gas outlet cavity via the primary gas pump, and finally discharged out from the gas outlet nozzle.

Abstract: An actuating and sensing module is disclosed and includes an actuating device, a first substrate, a second substrate, a valve membrane and a sensor stacked sequentially. The first substrate includes an intake channel, an exhaust channel, an inlet and an outlet. The valve membrane is disposed between the first substrate and the second substrate and includes an intake valve and an exhaust valve to insulate the intake channel and the exhaust channel, respectively. The actuating device is disposed to seal a through slot of the second substrate to form a compressing chamber. The inlet, the intake channel, the compressing chamber, the exhaust channel and the outlet are in communication with each other to define a gas flow loop. The sensor is disposed in the gas flow loop. While the actuating device drives gas from the outside, the gas is transported into the gas flow loop and sensed by the sensor.

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 and 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 stacked on each other. A synchronously-deformed structure is defined by the flexible plate and the communication plate. The deformable substrate is bent in the direction toward the vibration plate. 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.

Abstract: A piezoelectric actuator includes a suspension plate, an outer frame, at least one bracket and a piezoelectric ceramic plate. The suspension plate is a square structure. The length of the suspension plate is in a range between 4 mm and 8 mm, and the suspension plate is permitted to undergo a curvy vibration from a middle portion to a periphery portion. The outer frame is arranged around the suspension plate. The at least one bracket is connected between the suspension plate and the outer frame for elastically supporting the suspension plate. The piezoelectric ceramic plate is a square structure and has a length not larger than a length of the suspension plate. The piezoelectric ceramic plate is attached on a first surface of the suspension plate. When a voltage is applied to the piezoelectric ceramic plate, the suspension plate is driven to undergo the curvy vibration.

Abstract: A miniature fluid control device includes a gas inlet plate, a resonance plate and a piezoelectric actuator. The gas inlet plate includes at least one inlet, at least one convergence channel and a central cavity. A convergence chamber is defined by the central cavity. The resonance plate has a central aperture. The piezoelectric actuator includes a suspension plate, an outer frame and a piezoelectric ceramic plate. A gap is formed between the resonance plate and the piezoelectric actuator to define a first chamber. When the piezoelectric actuator is driven and after the gas is fed into the miniature fluid control device through the inlet of the gas inlet plate, the gas is sequentially converged to the central cavity through the convergence channel, transferred through the central aperture of the resonance plate, introduced into the first chamber, transferred downwardly through the piezoelectric actuator, and exited from the miniature fluid control device.
