    Abstract: A micro (thin film type) valve apparatus for controlling fluid flow and its rate using a microbead and a method for controlling the apparatus are provided. The microbead is moved by the magnetic forge generated by upper and lower electromagnets disposed on the top and bottom surface of the body or by the electric field generated by upper and lower electrode plates disposed on the top and bottom surface of the body, thereby interconnecting or blocking flow channels in the body. The micro valve apparatus and the method for controlling the same are suitable for thin film type diagnostic assay devices, such as lab-on-chips, protein chips, or DNA chips, for detecting small quantities of analytes in fluids, and more suitable for interconnecting or blocking channels formed in thin disk type apparatus including general CD-ROMs,DVDs, bioCDs, and bio DVDs.

    Abstract: A microelectromechanical device with integrated control of a flow of a fluid has a first sheet (1) and a second sheet (2) which are arranged on each other and interconnected. The first sheet (1) has, in its surface engaging the second sheet (2), a flow duct system (9) for the fluid. Further the device has an inlet (10) to the flow duct system, an outlet (11) from the flow duct system and at least one microsensor (17a), which is mounted in the flow duct system (9) and arranged to react to the fluid. The first sheet (1) has a first layer (3) of polymer material which engages the second sheet (2) and in which the flow duct system (9) is formed, and an electrically conductive layer (5) on which the layer of polymer material is formed and which is quickly heatable so as to quickly heat the fluid in the flow duct system (9) by heat conduction.

    Abstract: An improved microvalve device (300) is configured to provide a more robust and durable operation to withstand the demands of various operating environments. The microvalve may comprise a valve seat (302) and a diaphragm (304), with the diaphragm operated by an external actuator device (308), such as a bladder, through various mechanisms of actuation, such as direct and indirect mechanisms, that are separate from the microvalve. Through use of the various mechanisms of actuation, the actuator device is configured to apply forces on the diaphragm to suitably move the diaphragm to open and close the microvalve. The valve seat and diaphragm can be configured to provide the microvalve with a plurality of openings configured to permit flow thereinbetween. In addition, the microvalve may be configured to facilitate uni-directional or bi-directional flow. Further, a plurality of microvalves can be cascaded together in a parallel and/or series configuration, with each valve having similar or different flow characteristics, and being selectively operated. The microvalve can also include a combination gate valve configuration and a bladder configuration to provide high frequency response characteristics in addition to stability and reduction in leak flow.
