    Abstract: A blood pressure detection device manufactured by a semiconductor process includes a substrate, a microelectromechanical element, a gas-pressure-sensing element, a driving-chip element, an encapsulation layer and a valve layer. The substrate includes inlet apertures. The microelectromechanical element and the gas-pressure-sensing element are stacked and integrally formed on the substrate. The encapsulation layer is encapsulated and positioned on the substrate. A flowing-channel space is formed above the microelectromechanical element and the gas-pressure-sensing element. The encapsulation layer includes an outlet aperture in communication with an airbag. The driving-chip element controls the microelectromechanical element, the gas-pressure-sensing element and valve units to transport gas. The gas is introduced into the flowing-channel space through the inlet apertures and transported into the airbag through the outlet aperture, to inflate the airbag for blood pressure measurement, and a detection datum of blood pressure outputted by the gas-pressure-sensing element is transmitted to the microprocessor to calculate.

    Abstract: A driving system for driving piezoelectric pump includes one or more mechanical devices and a driving circuit system electrically connected to the at least one mechanical device. The driving circuit system includes a pump-driving unit, a linear voltage-stabilizing unit, a microcontroller unit, a current-sensing unit, and a connection unit. The microcontroller unit generates a first signal, a second signal, and a third signal, and the pump-driving unit receives these signals to drive the mechanical device. The current-sensing unit receives a fourth signal transmitted by the pump-driving unit to obtain an actuation current value of the mechanical device. The linear voltage-stabilizing unit, the current-sensing unit, and the microcontroller unit are coupled to each other through a fifth signal and a sixth signal. The connection unit and the microcontroller unit are coupled to each other through a reset signal, a seventh signal, and an eighth signal provided by the microcontroller unit.

    Abstract: A breast pump includes a main body, a breast milk suctioning shield, and one or more air pumps. The breast milk suctioning shield is assembled in an accommodation space of the main body and detachably connected to the main body. A front end of the breast milk suctioning shield has a breast shielding portion, and a nipple passage extends from a rear end of a center portion of the breast shielding portion. One or more deformable members and a non-deformable supporting member are assembled with an annular connection portion located between the breast shielding portion and the nipple passage. The air pump has an intake port and an exhaust port. The intake port is controlled by a first valve controller to suction the nipple passage and generate a negative pressure, and the exhaust port is controlled by a second valve controller to inflate or deflate the deformable member.

    Abstract: A miniature gas detection system includes a separation flow channel fabricated by semiconductor processes and a filling material disposed in the main flow channel of the separation flow channel to perform adsorption and separation on compositions of compounds contained in the gas introduced into the main flow channel. Each detection flow channel is formed with a monitoring chamber, and a micro-electromechanical systems pump is formed on the bottom portion of the monitoring chamber. In each monitoring chamber, a light emitted from the light emitting element is reflected by the two mirrors and received by the light detection element. Therefore, the light detection elements obtain and output spectra of the compositions of compounds contained in the gas according to the differences in optical adsorptions of the compositions of compounds for lights with different wavelengths, so as to analyze and determine the type of the gas contained in the compositions of compounds.
