Abstract: A miniature fluid control device includes a piezoelectric actuator, a gas collecting plate and a base. The piezoelectric actuator includes a suspension plate, an outer frame, at least one bracket and a piezoelectric ceramic plate. The suspension plate is a square plate. The outer frame is arranged around the suspension plate. A surface of the outer frame and a surface of the suspension plate are coplanar with each other. The gas collecting plate is a frame body with an accommodation space. The base includes a gas inlet plate and a resonance plate. The base is disposed within the accommodation space to seal the piezoelectric actuator. An adhesive layer is arranged between the second surface of the outer frame of the piezoelectric actuator and the resonance plate. Consequently, a depth of a compressible chamber between the piezoelectric actuator and the resonance plate is maintained.

Abstract: A piezoelectric actuator includes a suspension plate, a piezoelectric ceramic plate, an outer frame and a bracket. The suspension plate is permitted to undergo a curvy vibration from a middle portion to a periphery portion. The piezoelectric ceramic plate is attached on the suspension plate. When a voltage is applied to the piezoelectric ceramic plate, the suspension plate is driven to undergo the curvy vibration. The outer frame is arranged around the suspension plate. The bracket is connected between the suspension plate and the outer frame for elastically supporting the suspension plate, and includes an intermediate part formed in a vacant space between the suspension plate and the outer frame and in parallel with the outer frame and the suspension plate, a first connecting part arranged between the intermediate part and the suspension plate, and a second connecting part arranged between the intermediate part and the outer frame.

Abstract: A miniature pneumatic device includes a miniature fluid control device and a miniature valve device. The miniature fluid control device includes a gas inlet plate, a resonance plate, a piezoelectric actuator and a gas collecting plate. A first chamber is formed between the resonance plate and the piezoelectric actuator. After a gas is fed into the gas inlet plate, the gas is transferred to the first chamber through the resonance plate and then transferred downwardly. Consequently, a pressure gradient is generated to continuously push the gas. The miniature valve device includes a valve plate and a gas outlet plate. After the gas is transferred from the miniature fluid control device to the miniature valve device, the valve opening of the valve plate is correspondingly opened or closed and the gas is transferred in one direction. Consequently, a pressure-collecting operation or a pressure-releasing operation is selectively performed.

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.

Abstract: A miniature fluid control device includes a piezoelectric actuator and a housing. The piezoelectric actuator comprises a suspension plate, an outer frame, at least one bracket and a piezoelectric ceramic plate. The piezoelectric ceramic plate is attached on a first surface of the suspension plate and has a length not larger than that of the suspension plate. The housing includes a gas collecting plate and a base. The gas collecting plate is a frame body with a sidewall and comprises a plurality of perforations. The base seals a bottom of the piezoelectric actuator and has a central aperture corresponding to the middle portion of the suspension plate. When the voltage is applied to the piezoelectric actuator, the suspension plate is permitted to undergo the curvy vibration, the fluid is transferred from the central aperture of the base to the gas-collecting chamber, and exited from the perforations.

Abstract: An actuating and sensing apparatus includes a circuit board, a housing, an actuating device and a sensor. The housing is disposed on the circuit board and includes an entrance opening, an exit opening and a compartment. The compartment is in communication with an external environment of the housing through the entrance opening and the exit opening. The actuating device is disposed within the compartment and closing the exit opening. The sensor is disposed within the compartment and corresponding to the entrance opening. When the actuating device is enabled, a gas within the compartment is guided to the external environment outside the housing, and a pressure gradient is generated in the compartment so as to introduce a gas from the external environment outside the housing into the compartment through the entrance opening to make the gas detected by the sensor.

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.
