    Abstract: A gas detection device manufactured by a semiconductor process includes a substrate, a microelectromechanical element, a light-emitting element, a particle-sensing element, a gas-sensing element, a driving-chip element and an encapsulation layer. The driving-chip element controls driving operations of the microelectromechanical element, the light-emitting element, the particle-sensing element and the gas-sensing element, respectively. When the microelectromechanical element is enabled to actuate transportation of gas, the gas is introduced into the gas detection device through an inlet aperture of the substrate. Scattered light spots generated by the light beam of the light-emitting element irradiating on suspended particles contained in the gas are received by the particle-sensing element to generate a detection datum of the suspended particles. The gas-sensing element detects the gas passing through and generates a detection datum of hazardous gas contained in the gas. Finally, the gas is discharged from an outlet aperture of the encapsulation layer.

    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: An in-car air pollution prevention system is disclosed and includes plural gas detection modules and a gas conditioning device. The in-car gas detection modules and the out-car gas detection modules are provided for detecting the external gas and the air pollution source and transmitting the gas detection data respectively. A plurality of filtering and purification components are disposed within the gas conditioning device for filtering the external gas and the air pollution source. After the control drive unit compares the gas detection data, the gas conditioning device intelligently select and control the introduction or not introduction of the external gas. The plurality of in-car gas detection modules control the enablement of the gas guider of the gas conditioning device under a monitoring mechanism state. Whereby the gas pollution source in the interior space of the car is filtered through the filtering and purification component, and the gas pollution source is filtered and/or exchanged to generate clean air.

    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 guides a specified amount of gas to the gas sensor for obtaining plural monitored values, each of which is generated according to a result of detecting volatile organic compounds of the gas in each monitoring time interval by the gas sensor. All the monitored values obtained in a unit time period are added together and calculated, so that an average comparison value is obtained. If the average comparison value is determined greater than an injury threshold defined according to the VOC inhalation amount affecting the health of a human body, the actuating-and-sensing module issues a warning notification to notify the user to take protective measures.
