Abstract: According to the present invention, there is provided a micro-fluidic sensor system (6) including a micro-conduit (56) for carrying fluid therethrough having a flexible wall portion (18), at least one micro-fluidic actuator having a closed cavity, flexible mechanism defining a wall of the cavity (11) and flexible wall portion (18) of the micro-conduit for deflecting upon an application of pressure thereto, and expanding mechanism (14) disposed in the cavity for selectively expanding the cavity and thereby selectively flexing said expanding mechanism, and sensor mechanism in fluid communication with the micro-conduit for sensing the presence or absence of molecules. The present invention further provides for a micro-fluidic system for moving micro-fluid amounts including a micro-conduit and at least one micro-fluidic actuator in fluid communication with the micro-conduit.

Abstract: According to the present invention, there is provided a pulsating micro chamber including a walled chamber. The walled chamber further includes at least one pulsating portion actuable to pulse and change an interior volume of the walled chamber. The present invention further provides for a micro-fluidic pump including a micro conduit for carrying fluid therethrough and at least one actuating mechanism for peristaltically moving fluids through the micro conduit. The actuating mechanism includes a closed pocket adjacent to the conduit, a flexible mechanism defining a portion of a wall of the micro conduit, and an expanding mechanism disposed within the pocket for expanding a volume of the pocket and thereby flexing the flexible mechanism into the micro conduit thereby changing the volume of the conduit.

Abstract: According to the present invention, there is provided a micro-fluidic valve including a micro conduit for carrying fluid therethrough and at least one micro actuating mechanism for selectively deflecting at least a portion of a wall of the micro conduit occluding fluid flow through the micro conduit. Additionally, the present invention provides for a mono-stable micro-fluidic valve and for a bi-stable micro-fluidic valve.
