    Abstract: A driving circuit for a piezoelectrically actuated pump includes a boost converter, a control circuit and a voltage switch circuit. The boost converter outputs a constant voltage. The control circuit includes a voltage-division circuit, a comparator and a frequency adjustment circuit. The constant voltage is divided by the voltage-division circuit into a first voltage and a second voltage. The comparator compares first voltage with second voltage so as to output a positive voltage or a negative voltage. The voltage switch circuit receives and feedbacks positive voltage or negative voltage to the piezoelectric actuator load. The control circuit and the voltage switch circuit form a resonant circuit to control the piezoelectric actuator load according to the variety of minor voltage outputted form the piezoelectric actuator load. The frequency adjustment circuit detects and adjusts the variety of the minor voltage automatically so as to adjust operating frequency of the piezoelectric actuator load.

    Abstract: A gas transportation device is provided and includes an outer housing, a valve body and an actuator. The valve body includes a gas outlet plate, a valve plate and a first plate. The gas outlet plate includes plural outlet apertures, the first plate includes plural first orifices, the valve plate includes plural valve openings, the plural valve openings are misaligned with the plural first orifices and corresponding in position to the plural outlet apertures. The actuator having an actuating component in rectangular shape is stacked and disposed on the valve body. When the actuator is driven, through the structure that the plural first orifices and the plural valve openings are misaligned, the valve body is operated to open a flow path when an airflow is in a forward direction, and the valve body is operated to seal the flow path when the airflow is in a reverse direction.

    Abstract: A micro pump includes a base plate, a valve membrane, an upper covering plate and a pump core module. The valve membrane is disposed in a valve membrane accommodation slot of the base plate, seals a fluid channel of the base plate and includes a valve aperture where a protruding portion of the base plate extended through. The upper covering plate is accommodated in an upper covering plate accommodation slot of the base plate and includes a fluid relief aperture sealed by the valve membrane, a fluid converging groove and a fluid converging channel between the fluid converging groove and a fluid-outlet channel of the base plate. The pump core module is accommodated within a pump accommodation slot of the base plate. By actuating the pump core module, the fluid passes through the fluid channel, the valve aperture, the fluid converging groove, and is discharged out through the fluid-outlet channel.

    Abstract: A miniature fluid transportation device is provided and includes a convergence component, a valve component, an outlet plate and a plurality of fluid transportation actuation components. The plurality of fluid transportation actuation components are disposed on the convergence component so as to transport the fluid to the convergence component. The convergence component guides the fluid transported by the fluid transportation actuation components to the outlet plate through the valve component. The outlet plate guides the fluid from different transportation actuation components back to the convergence component by a separation guiding block. The fluid is converged in a convergence central slot of the convergence component and is discharged out through a collection channel of the outlet plate. Consequently, the problem of interference owing to the convergence of the fluid transported by different fluid transportation actuation components can be avoided.

    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: An actuating and sensing module includes a first substrate, a second substrate, an actuating device and a sensor. The first and second substrates are stacked on each other as a gas flow channel is formed therebetween. The gas inlet, the gas flow channel and the gas outlet are in communication with each other to define a gas flow path. The actuating device is disposed in the gas outlet of the second substrate and electrically connected to a control circuit to obtain driving power. The sensor is disposed in the gas flow path and misaligned with the gas inlet. The sensor is spaced apart from the actuating device and is electrically connected to the control circuit. Being driven by the actuating device, the gas is transported from the outside into the gas flow path and monitored by the sensor.
