Abstract: An air circulation control device includes a casing and at least one air pump. The casing includes at least one entrance opening, at least one exit opening and an accommodation space. Each air pump is disposed in and closes the corresponding entrance opening. Each air pump includes a first protective film that is a waterproof and dustproof film structure allowing gas to pass therethrough. When the air pump is enabled, the gas is introduced into the accommodation space through the entrance opening and discharged from the accommodation space through the exit opening, so that the gas is circulated.

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 miniature gas control device is disclosed and includes a miniature gas transportation device and a miniature valve device. The miniature gas transportation device includes a protective film, a gas inlet plate, a resonance plate and a piezoelectric actuator stack sequentially. The miniature valve device includes a gas collecting plate, a valve film and a gas outlet plate stacked sequentially. By driving the piezoelectric actuator of the miniature gas transportation device, the gas flows into the miniature gas transportation device from the gas inlet plate, then the gas flows into the miniature valve device through the resonance plate, and the valve opening of the valve film is selectively opened or closed in response to a direction of the gas unidirectionally flowing among the perforations and chambers of the gas collection plate and the gas outlet plate, so as to perform a pressurizing operation and a pressure-releasing operation selectively.

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, 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: 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.
