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 module includes a first substrate, a second substrate, an actuating device and a sensor. A gas flow channel is formed by stacking the first substrate and the second substrate. The gas inlet, the gas flow channel and the gas outlet are in communication with each other to define a gas flow loop. The actuating device is disposed in the gas inlet of the second substrate and electrically connected to a control circuit to obtain a driving power. The sensor is disposed in the gas flow loop and electrically connected to a control circuit of the first substrate to transmit sensed data. While the actuating device drives outside gas from the outside, the gas is transported into the gas flow loop and sensed by the sensor.

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 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.
