摘要： The invention uses a solenoid to apply a force to a fluid in communication with a near constant volume fluidic linkage. A voltage applied to the solenoid pressurizes the fluid causing the constant volume fluidic linkage to displace. In this way, a transducer is created that converts voltage into a displacement. To create a motor, the displacement is used to stop the application of the voltage to the solenoid allowing the constant volume fluidic linkage to return to an initial state. The return to the initial state then triggers the re-application of the voltage. In this way, the voltage source is used to create a reciprocating motion.

摘要： A method is provided for fabricating a constriction region in a channel of a microfluidic device. The method includes the steps of introducing a pre-polymer mixture including a monomer, cross-linking agent and photoinitiator into the channel. The pre-polymer mixture is polymerized at a localized area of the channel so as to shrink and solidify the liquid mixture. The solidified and shrunken liquid mixture provides the constriction region in the channel.

摘要： Microfluidic devices provide substances to a mass spectrometer. The microfluidic devices include first and second surfaces, at least one microchannel formed by the surfaces, and an outlet at an edge of the surfaces which is recessed back from an adjacent portion of the edge. Hydrophilic surfaces and/or hydrophobic surfaces guide substances out of the outlet. A source of electrical potential can help move substances through the microchannel, separate substances and/or provide electrospray ionization.

摘要： Arranged in a hydraulic circuit is a valve with an L-shaped duct arrangement, which is formed by a transverse duct 2 and a longitudinal duct 3. Formed in extension of the longitudinal duct 3 is a holding and guiding bore 4, in which a throttling element, comprising a throttle slide 10 and a valve piston 21 that can be displaced therein, can be displaced longitudinally. The valve piston 21 has a passage hole 25, which is connected to the interior of the throttling element and two proportionate annular chambers 17a and 17b. Of these, the proportionate annular chamber 17b is connected to a pilot control valve via a control duct 19. Depending on the direction and pressure of the hydraulic fluid flowing through the L-shaped duct arrangement, the throttling element is moved in or out and extended or compressed in the process. In this way, the valve arrangement acts as a throttling valve in the event of flow in the direction from the transverse duct 2 to the longitudinal duct 3, while the flow in the opposite flow direction is not throttled.

摘要： A micro channel unit having a shape designed to reduce a pressure drop when fluid passes through a connecting channel portion is provided. The micro channel unit includes a micro channel with a width of micrometer dimensions through which liquid flows. The micro channel includes a plurality of straight channel portions and connecting channel portions that connect each pair of adjacent straight channel portions. The connecting channel portions are wider than the straight channel portions connected by the connecting channel portions. The use of the micro channel unit can reduce the pressure drop when fluid passes through the connecting channel portions, thereby reducing the amount of power required to drive the fluid flow and further enabling miniaturization of microfluidic devices such as pumps and peripheral devices.
