<p>A microfluidic device (10) and method using the same is provided for self-regulating the flow of fluid therethrough. The device (10) includes a body (12) defining first and second flow channels (14, 24). The first flow channel (14) has an input (16) for receiving the fluid and an output (20). The second flow channel (24) has an input (30) for receiving a compensating fluid to modify the value of the property of the fluid and an output (44) communicating with the first flow channel. Polymeric material (56) is disposed in the first flow channel (14) downstream of the output (44) of the second flow channel (24). The polymeric material has a volume responsive to the value of the property of the fluid. A valve (54) is disposed in the second flow channel (24) and is movable in response to the volume of the material (56) so as to control the compensating fluid flowing.</p> |
