Abstract:
Provided is a liquid droplet collection device including: a substrate having a hydrophobic surface; and a hydrophilic channel arranged in the hydrophobic surface, wherein the hydrophilic channel includes: a first-generation channel including a plurality of tapered channel portions radially extending from an origin point and monotonically tapering with increasing distance from the origin point; and a second-generation channel that includes a plurality of tapered channel portions radially extending from an origin point and monotonically tapering with increasing distance from the origin point, and is scaled down in size as compared to the first-generation channel, wherein the second-generation channel is joined to the first-generation channel to face the same direction as the first-generation channel, and wherein one of the tapered channel portions of the second-generation channel overlaps a distal end portion of one of the tapered channel portions of the first-generation channel, and the hydrophilic channel monotonically tapers from a proximal end of one of the tapered channel portions of the first-generation channel to a distal end of one of the tapered channel portions of the second-generation channel.
