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 micro pump having noise-reduced pressure-releasing structure includes a convergence plate, a valve sheet, a chamber plate, and a micro pump. The convergence plate has a convergence outlet and a discharge outlet. The valve sheet has a valve hole and a discharge recessed portion. The chamber plate has a recessed hole, a fluid determine hole, fluid through holes, and a receiving trough. The micro pump is in the receiving trough. During operation of the micro pump, the fluid is firstly transmitted to the fluid through hole and the fluid determine hole to push the valve sheet, and the fluid determine hole pushes the discharge recessed portion to block the discharge outlet. Then, since the pressure of the fluid at the fluid through hole pushes the valve sheet, the fluid flows through the valve hole so as to be discharged out from the convergence outlet.

Abstract: A micro pump is disclosed and includes a fluid-converging plate, a valve membrane, a fluid-outlet plate and a pump core module. The fluid-converging plate includes an inner recess, a protruding portion and a fluid-converging aperture. The protruding portion is disposed at a center of the inner recess. The valve membrane includes a valve aperture. The protruding portion of the fluid-converging plate abuts against the valve aperture. A fluid-converging chamber is formed between the valve membrane and the fluid-converging plate. The fluid-outlet plate in a ring shape includes a fluid-outlet channel. The valve aperture is in fluid communication with the fluid-outlet channel. When the fluid is inhaled into the pump core module, the fluid flows to the fluid-converging chamber through the fluid-converging aperture and then pushes out the valve membrane to flow into the fluid-outlet channel of the fluid-outlet plate through the valve aperture. Thereby the fluid transportation is achieved.

Abstract: A piezoelectric actuator for a miniature fluid transportation device is provided and includes a piezoelectric actuating plate and a piezoelectric element. The piezoelectric actuating plate includes a suspension plate, an outer frame, and brackets. The suspension plate has a first thickness. The outer frame is arranged around the suspension plate and has a third thickness. Each of the brackets is connected between the suspension plate and the outer frame and has a fourth thickness. The third thickness is larger than the first thickness, and the first thickness is larger than the fourth thickness. The suspension plate, the outer frame and the brackets are constructed to form different stepped structures to minimize the thickness of the brackets, enhance the elasticity of the brackets. Thus, displacement of the suspension plate in the vertical direction is enhanced and the transportation efficiency of the miniature fluid transportation device is intensified.

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.
