Abstract: A miniature fluid control device includes a gas inlet plate, a resonance plate and a piezoelectric actuator. The gas inlet plate includes at least one inlet, at least one convergence channel and a central cavity. A convergence chamber is defined by the central cavity. The resonance plate has a central aperture. The piezoelectric actuator includes a suspension plate, an outer frame and a piezoelectric ceramic plate.

Abstract: A VOC detecting and warning method is provided. Firstly, an actuating-and-sensing module having a gas transportation actuator and a gas sensor is provided. Then, the gas transportation actuator is enabled to guide a specific amount of gas to the gas sensor in each monitoring time interval, so that each monitored value of a VOC in the specific amount of the gas corresponding to each monitoring time interval is acquired. A plurality of the monitoring time intervals define a time unit. Then, the monitored values during the time unit are added up to obtain a metabolism comparison value. If the metabolism comparison value is larger than a warning threshold value that is defined according to an upper limit of the VOC that a human subject inhales per time unit, the actuating-and-sensing module issues an emergency call, thereby providing a user with a protective measure.

Abstract: A gas detecting device includes an actuating-and-sensing module, a driving controller, a data storage device and a data processor. The actuating-and-sensing module includes a first gas sensor, a second gas sensor and a gas transportation actuator. The driving controller controls the actuations and non-actuations of the first gas sensor, the second gas sensor and the gas transportation actuator. The first gas sensor measures the target gas and transmits first gas measured information to the data storage device. The second gas sensor measures the target gas and transmits second gas measured information to the data storage device. The data processor calculates concentrations of the gases in the target gas by comparing the information stored in a gas database, the first gas measured information and the second gas measured information.

Abstract: A driving system includes a voltage conversion module, a frequency control module, a voltage switching module and a detecting module. The voltage conversion module is used for converting a first DC voltage into a second DC voltage. The frequency control module searches a resonant working frequency of a piezoelectric actuator through circuit oscillation and generates a switching signal according to the resonant working frequency. According to the switching signal, the voltage switching module converts the second DC voltage into an AC voltage so as to drive the piezoelectric actuator. The detecting module includes a gas pressure sensor and a microcontroller. The gas pressure sensor generates a detected gas pressure value according to a result of detecting a gas pressure of the piezoelectric pump. The microcontroller controls the voltage conversion module to adjust the output voltage. Consequently, the gas pressure of the piezoelectric pump is adjusted.

Abstract: A micro-gas pressure driving apparatus includes a miniature gas transportation module and a miniature valve module. The miniature gas transportation module includes a gas inlet plate, a fluid channel plate, a resonance membrane and a piezoelectric actuator. A first chamber is defined between the resonance membrane and the piezoelectric actuator. After the piezoelectric actuator is activated to feed a gas through the gas inlet plate, the gas is transferred to the first chamber through the fluid channel plate and the resonance membrane and then transferred downwardly. Consequently, a pressure gradient is generated to continuously push the gas. The miniature valve module includes a gas collecting plate, a valve membrane and a gas outlet plate. After the gas is transferred from the miniature gas transportation module to the gas-collecting chamber, the gas is transferred in one direction, so that a pressure-collecting operation or a pressure-releasing operation is selectively performed.
