    Abstract: A portable device for monitoring environmental air quality includes a main body and at least one actuating and sensing module. The actuating and sensing module is disposed in the main body. The actuating and sensing module includes a carrier, at least one sensor, at least one actuating device, a driving and transmitting controller and a battery. The sensor, the actuating device, the driving and transmitting controller and the battery are disposed on the carrier. The actuating device is enabled to transport fluid to flow toward the sensor so as to make the fluid measured by the sensor and transmit an output data of the monitored data to a connection device. The information carried in the output data may be displayed, stored and transmitted by the connection device, whereby users can take precautions against the air pollution immediately to prevent from the ill influence on human health.

    Abstract: A gas transportation device includes an inlet plate, a substrate, a resonance plate, an actuating plate, a piezoelectric component and an outlet plate stacked sequentially. The gas transportation device includes a valve disposed within at least one of the inlet of the inlet plate and the outlet of the outlet plate. A first chamber is formed between the resonance plate and the actuating plate, and a second chamber is formed between the actuating plate and the outlet plate. When the piezoelectric component drives the actuating plate, a pressure gradient is formed between the first and second chambers and the valve is opened. Accordingly, gas is inhaled into the convergence chamber via the inlet, transported into the first chamber through a central aperture of the resonance plate, transported into the second chamber through a vacant space of the actuating plate, and then discharged out from the outlet, so as to transport the gas.

    Abstract: A micro fluid actuator includes an orifice layer, a flow channel layer, a substrate, a chamber layer, a vibration layer, a lower electrode layer, a piezoelectric actuation layer and an upper electrode layer, which are stacked sequentially. An outflow aperture, a plurality of first inflow apertures and a second inflow aperture are formed in the substrate by an etching process. A storage chamber is formed in the chamber layer by the etching process. An outflow opening and an inflow opening are formed in the orifice layer by the etching process. An outflow channel, an inflow channel and a plurality of columnar structures are formed in the flow channel layer by a lithography process. By providing driving power which have different phases to the upper electrode layer and the lower electrode layer, the vibration layer is driven to displace in a reciprocating manner, so as to achieve fluid transportation.

    Abstract: A fluid system includes a fluid active region, a fluid channel, a convergence chamber and plural valves. The fluid active region includes one or plural fluid-guiding units. Each fluid-guiding unit includes an inlet plate, a substrate, a resonance plate, an actuating plate, a piezoelectric element and an outlet plate, which are stacked sequentially. The piezoelectric element is attached on the actuating plate. When the piezoelectric element drives a bending resonance of the actuating plate, the fluid is transported into the fluid-guiding units and pressurized to be discharged out. The fluid channel includes plural branch channels. The fluid discharged from the fluid active region is split by the branch channels. The convergence chamber is in communication with the fluid channel. The valves are disposed in the branch channels. The fluid is transported through the branch channels according to the open/closed states of the valves.
