    Abstract: A driving system for driving piezoelectric pump includes one or more mechanical devices and a driving circuit system electrically connected to the at least one mechanical device. The driving circuit system includes a pump-driving unit, a linear voltage-stabilizing unit, a microcontroller unit, a current-sensing unit, and a connection unit. The microcontroller unit generates a first signal, a second signal, and a third signal, and the pump-driving unit receives these signals to drive the mechanical device. The current-sensing unit receives a fourth signal transmitted by the pump-driving unit to obtain an actuation current value of the mechanical device. The linear voltage-stabilizing unit, the current-sensing unit, and the microcontroller unit are coupled to each other through a fifth signal and a sixth signal. The connection unit and the microcontroller unit are coupled to each other through a reset signal, a seventh signal, and an eighth signal provided by the microcontroller unit.

    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 air-cooling heat dissipation device is provided for removing heat from an electronic component. The air-cooling heat dissipation device includes a supporting substrate, an air pump and a heat sink. The supporting substrate includes a top surface, a bottom surface, an introduction opening and a thermal conduction plate. The thermal conduction plate is located over the top surface of the supporting substrate and aligned with the introduction opening. The electronic component is disposed on the thermal conduction plate. The air pump is fixed on the bottom surface of the supporting substrate and aligned with the introduction opening. The heat sink is attached on the electronic component. When the air pump is enabled, an ambient air is introduced into the introduction opening to remove the heat from the thermal conduction plate.

    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 fluid control device includes a piezoelectric actuator, a housing and a glue body. The piezoelectric actuator includes a suspension plate, an outer frame, a bracket and a piezoelectric element. The housing includes an outlet plate and a base. The outlet plate accommodates the piezoelectric actuator and the base includes an inlet plate and a resonance plate. The glue body is arranged between the outer frame and the resonance plate to maintain a gap formed therebetween. The suspension plate is made of a material having a linear expansion coefficient less than a linear expansion coefficient of the piezoelectric element. The suspension plate has a specified hardness to maintain a curved shape after being heated, and the linear expansion coefficient of the suspension plate is different from a linear expansion coefficient of the resonance plate, so that an effective deformation displacement between the suspension plate and the resonance plate is obtained.
