Abstract: A micro piezoelectric pump module includes a microprocessor, a driving element, and a piezoelectric pump. The driving element is connected to the microprocessor to receive a modulating signal and a control signal and to output a driving signal. The driving signal includes a driving voltage and a driving frequency. The piezoelectric pump is actuated by the driving signal, and the piezoelectric pump is set to be actuated at an actuation frequency and be applied with an actuation voltage value. The microprocessor drives the driving element to output the driving voltage having an initial voltage value at the driving frequency to the piezoelectric pump, and adjusts the driving frequency to the same with the actuation frequency. After the driving frequency is adjusted to reach the actuation frequency, the microprocessor drives the driving element to gradually increase the initial voltage value to reach the actuation voltage value.

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.

Abstract: A miniature piezoelectric pump module is provided and includes a piezoelectric pump, a microprocessor, a driving component and a feedback circuit. The piezoelectric pump includes two electrodes and a piezoelectric element and has the best efficiency while operating under an ideal operating voltage. The driving component is electrically connected to the microprocessor and the piezoelectric pump and includes a transform element and an inverting element. The transform element outputs an effective operating voltage to the piezoelectric pump. The inverting element controls the two electrodes to receive the effective operating voltage or to be grounded. The piezoelectric element is subjected to deformation for transporting fluid due to piezoelectric effect. The feedback circuit generates a feedback voltage according to the effective operating voltage. The microprocessor adjusts the modulation signal according to the feedback voltage for adjusting the effective operating voltage outputted by the transform element to approach the ideal operating voltage.

Abstract: An actuating and sensing module includes a first substrate, a second substrate, an actuating device and a sensor. The first and second substrates are stacked on each other as a gas flow channel is formed therebetween. The gas inlet, the gas flow channel and the gas outlet are in communication with each other to define a gas flow path. The actuating device is disposed in the gas outlet of the second substrate and electrically connected to a control circuit to obtain driving power. The sensor is disposed in the gas flow path and misaligned with the gas inlet. The sensor is spaced apart from the actuating device and is electrically connected to the control circuit. Being driven by the actuating device, the gas is transported from the outside into the gas flow path and monitored by the sensor.

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.
