Embodiment Construction

[0103] Wettability is a property that characterizes the interaction between a material surface and a liquid. Based on differences in wettability within a single material, when a fluid contacts a surface of a material, it is either absorbed or repelled by the surface of the material. There are two states of wettability: liquid absorption and liquid repellency. The liquid wettability of the material surface and the contact angle α of the fibers of the material for a specific fluid, the geometry of the pore structure characterized by the average pore radius r (note: for the fabric structure, the pore radius can be estimated as two distance between adjacent fiber peaks) and the properties of the liquid above it (surface tension γ and hydraulic pressure P L ) related. Both the absorption and repellency of liquids can be roughly determined by an important value S called the wettability value:

[0104]

[0105] If S > 0, the liquid will be absorbed by the fabric. If S < 0, the...

Abstract

An apparatus (100) and method is presented for the management of fluid flow utilizing different adjacent wettability regions (102, 104) to form a fluidic network structure on a substrate (106). The fluidic network structure may include liquid-absorptive fluidic channels (118), where the fluid can flow within these channels (118) and be removed from the substrate (106). Fluid can be moved by gravitational force, compression force, capillary force and surface tension force.

[0007] Notification of matters subject to copyright protection [0008] Not applicable. technical field [0009] The technology of the present disclosure relates generally to fluid management, and more particularly, to fluid flow management utilizing regions of different adjacent wettability to form a fluid network structure on a substrate. Background technique [0010] Sweating is the main means of body temperature regulation. During sweating, sweat (mainly composed of water) is secreted into the skin and heat is removed from below the epidermis by the evaporation of th...
