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: A gas detecting module includes a carrying plate, a sensor, a compartment body and an actuator. The carrying plate has a substrate and a gas opening. The compartment body is divided into a first compartment and a second compartment by a partition plate. The first compartment has an opening. The second compartment has an outlet and accommodates the actuator. The bottom of the compartment body has an accommodation recess receiving the carrying plate, whereby the gas opening is aligned with the outlet, and the sensor packaged on the substrate is disposed within the first compartment through the opening. The partition plate has a notch. The gas detecting module is assembled in a slim-type portable device having a casing. The casing has an inlet aligned with the first compartment. As the actuator is actuated, ambient gas is inhaled into the first compartment, and the sensor detects the gas flowing therethrough.

Abstract: A portable gas detecting device includes at least one detecting chamber, at least one gas sensor and at least one actuator. The gas sensor is disposed in the detecting chamber and configured for monitoring gas inside the detecting chamber. The actuator is disposed in the detecting chamber and includes a piezoelectric actuator. When an actuating signal is applied to the piezoelectric actuator and the piezoelectric actuator generates a resonance effect, the gas outside the detecting chamber is introduced into the detecting chamber for sampling. The actuator is driven by an instantaneous sampling pulse to control a trace of gas to flow into the detecting chamber for forming a stable airflow environment. In the stable airflow environment, a gas molecule is dissolved in or bonded to a reaction material on a surface of the gas sensor for reacting.
