Abstract: A gas transportation device is provided and includes a plurality of flow guiding units. Each of the flow guiding units includes an inlet plate, a substrate, a resonance plate, an actuating plate, a piezoelectric component, an outlet plate and a valve, which are sequentially stacked. A convergence chamber is formed between the resonance plate and the inlet plate. The actuating plate has a suspension part, an outer frame and a plurality of interspaces. The piezoelectric component is attached on a surface of the suspension part. Gas is inhaled into the convergence chamber via an inlet aperture of the inlet plate, is transported into a first chamber via a central aperture of the resonance plate, is further transported into a second chamber via the interspaces, and is discharged out from an outlet aperture of the outlet plate. The gas is transported by the flow guiding units disposed in a specific arrangement.

Abstract: A nasal-plug filter device including a device body, a filter, a first actuator, a second actuator, and a gas sensor is provided. The device body has a ventilating channel, and the ventilating channel has an inlet end and an outlet end. The filter is disposed at the outlet end. The first actuator is disposed at the inlet end for being driven to transmit gas outside the device body into the device body. The second actuator is stacked on and bonded to the first actuator, and the second actuator is driven to transmit the gas transmitted by the first actuator to the filter to be filtered and purified. The gas sensor is disposed at the outlet end for detecting a gas quality of the gas at the outlet end. A connection element may be provided for connecting two nasal-plug filter devices with each other.

Abstract: An electronic cigarette includes a power supply device, an atomizer, a liquid storage structure, a fluid transportation device, a sensing unit, a casing and a mouthpiece. The atomizer includes an electric heater and a liquid conduit. The liquid storage structure includes a liquid container for storing a cigarette liquid. The fluid transportation device is in communication with the liquid container and the liquid conduit. The cigarette liquid is transferred to the liquid conduit through the fluid transportation device. The sensing unit includes an airflow sensor and an air pressure sensor for adjusting the speeds of atomizing the cigarette liquid and providing the cigarette liquid. After an airflow is fed into an entrance of the casing, the airflow passes through an airflow chamber and the sensing unit along an airflow path. The mouthpiece seals an end of the casing and in communication with the airflow path.

Abstract: A micro-electromechanical fluid control device includes at least one flow guiding unit. The at least one flow guiding unit includes an inlet plate, a substrate, a resonance membrane, an actuating membrane and an outlet plate sequentially stacked. A first chamber is defined between the resonance membrane and the actuating membrane and a second chamber is defined between the actuating membrane and the outlet plate. While the piezoelectric membrane of the flow guiding unit drives the actuating membrane, a fluid is inhaled into the convergence chamber via the inlet of the inlet plate, transported into the first chamber via the central aperture of the resonance membrane, transported into the second chamber via a vacant space of the actuating membrane, and discharged out from the outlet of the outlet plate, so as to control the fluid to flow.
