    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 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: 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 portable electronic device includes a casing and an actuating and sensing module. The casing includes at least one inlet aperture, at least one vent aperture, a first chamber, a second chamber and at least one communication channel. The communication channel is connected between the first chamber and the second chamber. The actuating and sensing module includes an actuating device and a sensor. The actuating device is disposed within the first chamber and closes the inlet aperture. The actuating device further includes a first protective film. The sensor is disposed within the second chamber. When the actuating device is enabled, a gas is guided into the first chamber through the inlet aperture, and the gas is transferred to the second chamber through the communication channel so as to be monitored by the sensor. After the gas is monitored, the gas is outputted from the vent aperture.
