Claim:
1. A micro-fluidic device comprising at least two paper flow path layers providing fluid flow in substantially parallel planar directions, and at least two fluid actuated valves positioned between the at least two paper flow path layers, said at least two fluid actuated valves for providing autonomous flow, said at least two fluid actuated valves are commonly coupled to a flow path, wherein said at least two fluid actuated valves comprise a first set of opposing valves with a first fluidic channel between them coupled to one of said two paper flow path layers while a second set of opposing valves are coupled to said first set of two opposing valves with a second fluidic channel between coupled to another of said two paper flow path layers for providing said autonomous flow, the first fluidic channel being coupled to said second fluidic channel at a common point on a third fluidic channel.
