Abstract: A capillary structure for passive, directional fluid transport, includes a capillary having a forward direction and a backward direction extending in an x-y plane and a depth extending in a z-direction, the capillary including first and second capillary units each having a diverging section having a backward end, a forward end, and a width in the y-direction, wherein the width increases from the backward end to the forward end, wherein the backward end of the second capillary unit diverging section is connected to the forward end of the first capillary unit diverging section to form a transition section having a step decrease in width from the forward end of the first capillary unit diverging section to the backward end of the second capillary unit diverging section, and wherein the depth in the transition section is less than the depth in each diverging section.

Abstract: A material for distributing fluid can include a first side edge, a second side edge, a first end edge, and a second end edge. The material can include a first surface and a second surface opposite from the first surface. The material can be liquid impermeable and at least one of the first surface and the second surface include at least one channel. The channel can include a channel width, a channel length, and a channel depth. The channel width can be from 0.1 mm to 2.5 mm. The channel depth can be configured such that the channel does not extend completely through the material.

Abstract: A capillary structure for passive, directional fluid transport includes a capillary having a forward direction and a backward direction, the capillary including first and second capillary units each having a sequence of capillary components including a connective section in fluid communication with a diverging section, the diverging section having a forward side and dimensions inducing a concave meniscus in the forward direction, wherein the connective section of the second capillary unit is connected to the forward side of the diverging section of the first capillary unit to form at least one transition section, and wherein a change in the dimensions in the transition section induces in the backward direction a convex liquid meniscus or a straight liquid meniscus with an infinite radius of curvature.
