Abstract: A micro pump is disclosed and includes a fluid-converging plate, a valve membrane, a fluid-outlet plate and a pump core module. The fluid-converging plate includes an inner recess, a protruding portion and a fluid-converging aperture. The protruding portion is disposed at a center of the inner recess. The valve membrane includes a valve aperture. The protruding portion of the fluid-converging plate abuts against the valve aperture. A fluid-converging chamber is formed between the valve membrane and the fluid-converging plate. The fluid-outlet plate in a ring shape includes a fluid-outlet channel. The valve aperture is in fluid communication with the fluid-outlet channel. When the fluid is inhaled into the pump core module, the fluid flows to the fluid-converging chamber through the fluid-converging aperture and then pushes out the valve membrane to flow into the fluid-outlet channel of the fluid-outlet plate through the valve aperture. Thereby the fluid transportation is achieved.

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.

A flow channel is formed on the substrate. A conductive part and a movable part are formed on the supporting layer and the valve layer, respectively. A first chamber is formed at the interior of a base part and communicates to the hollow aperture. A supporting part is formed on the second insulation layer. A second chamber is formed at the interior of the supporting layer and communicates to the first chamber through the hollow aperture. A suspension part is formed on the vibration layer. By providing driving power sources having different phases to the bonding-pad layer, the suspension part moves upwardly and downwardly, and a relative displacement is generated between the movable part and the conductive part, to achieve fluid transportation.
