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 wearable blood pressure measuring device includes a wristband, a valve plate, a gas-collecting seat, a gas transportation device, an elastic medium and a pressure sensor. The wristband has a mounting zone. The mounting zone has a first accommodation recess, a second accommodation recess, a gas-collecting hole and a pressure-releasing hole. The first accommodation recess and the second accommodation recess are in fluid communication with each other through the gas-collecting hole. When the gas transportation device is enabled to transport the gas to the elastic medium, the elastic medium is inflated with the gas and expanded to push the pressure sensor to be in close contact with a measurement part of a user's body, thereby measuring a blood pressure value of a target artery through a scanning operation.

Abstract: A micro pump includes a base plate, a valve membrane, an upper covering plate and a pump core module. The valve membrane is disposed in a valve membrane accommodation slot of the base plate, seals a fluid channel of the base plate and includes a valve aperture where a protruding portion of the base plate extended through. The upper covering plate is accommodated in an upper covering plate accommodation slot of the base plate and includes a fluid relief aperture sealed by the valve membrane, a fluid converging groove and a fluid converging channel between the fluid converging groove and a fluid-outlet channel of the base plate. The pump core module is accommodated within a pump accommodation slot of the base plate. By actuating the pump core module, the fluid passes through the fluid channel, the valve aperture, the fluid converging groove, and is discharged out through the fluid-outlet channel.

Abstract: A gas transportation device includes a casing, a nozzle plate, a chamber frame, an actuator, an insulating frame and a conducting frame, which are stacked sequentially. The casing has a conduit protruding outwardly from the casing and aligned with a discharging opening. The conduit has a guiding channel and an outlet. The guiding channel has a cone shape and is tapered from an end proximate to the discharging opening to the other end proximate to the outlet. The actuator, the chamber frame and the suspension plate collaboratively define a resonance chamber. When the actuator is driven, the nozzle plate is subjected to resonance and the suspension plate of the nozzle plate vibrates in a reciprocating manner. Consequently, the gas is transported to a gas-guiding chamber through at least one gap and outputted from the discharging opening.

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.
