Abstract: A temperature regulation and flow control device is described. A web of material, e.g., for a wet suit, has a layer of gel particles embedded in a flow control layer, preferably a foam matrix. A water permeable neoprene layer covers the flow control layer and allows water to enter the suit. The flow of water in the suit is regulated by the expansion and contraction of the gel as it undergoes a volume phase transition in response to a change in temperature. When the diver is in cold water, the cold water enters the foam substrate and the gel expands, causing permeability (i.e., flow) to decrease. Flow is restricted in response to cooling, and the foam substrate expands and tightens the fit of the wet suit. In warmer water, an opposite effect occurs, whereby the gel contracts and flow increases. The gel contracts relaxing the fit of the suit. A gel having a particular volume phase transition critical temperature is selected in order to maintain body temperature in a particular environment. This technology also can be used to control temperature in other applications.

Abstract translation: 描述了温度调节和流量控制装置。 例如用于湿衣服的材料网具有嵌入流动控制层中的凝胶颗粒层，优选泡沫基质。 透水性氯丁橡胶层覆盖流动控制层，并允许水进入衣服。 衣服中的水流通过凝胶的膨胀和收缩来调节，因为它随着温度的变化而经历体积相变。 当潜水员处于冷水中时，冷水进入泡沫基质，凝胶膨胀，导致渗透性（即流动）降低。 响应于冷却而限制流动，并且泡沫基材膨胀并且紧固湿西装的配合。 在较热的水中，发生相反的效果，由此凝胶收缩和流动增加。 凝胶合约放松西装的适合。 选择具有特定体积相变临界温度的凝胶，以便在特定环境中保持体温。 该技术也可用于控制其他应用中的温度。
