Abstract: A passive microfluidic valve includes a first manifold portion having a first chamber; a first inlet fluidly coupled to the first chamber; and a second inlet. The valve also includes a second manifold portion in fluid communication with the first chamber via a channel. The second manifold portion includes a second chamber fluidly coupled to the first chamber and the second inlet. The valve further includes a flexible membrane disposed between the first manifold portion and the second manifold portion and separating the first chamber and the second chamber, the flexible membrane configured to modulate a flow rate of a media flowing between the first inlet and the second inlet in either direction in response to pressure of the media flow.
