The broader impact/commercial potential of this Small Business Innovation Research (SBIR) Phase II project is in increasing the comfort of people, such as athletes during their high intensity workouts and competitions, warehouse workers who require protective clothing in hot and humid environments, and safety (e.g. firemen and first responders) and military personnel who must endure extreme working conditions. Our revolutionary moisture management technology utilizes a novel 3D microfluidic transport principle to move sweat from the skin to the outside of clothing, where it can drip away or be controlled. Compared with conventional moisture wicking products which are based on capillary absorption, our technology allows fabric and apparel products to remain lightweight, always dry, highly breathable and never-saturated. ATACAMA?s technology is designed to provide the wearer an improved regulation of body temperature and comfort level during high intensity activities, contributing to both performance and safety. This project aims at solving the current problems of moisture-management products that are inadequate when dealing with large amount of moisture (e.g. sweat). In high sweat or high heat situations, apparel can become quickly saturated with moisture, leading to a wet, heavy, sticky feeling that impacts the performance of the wearer. Our proposed research aims to develop a broad range of textiles that can continuously transport moisture, so that fabric remain dry, breathable and lightweight during high intensity physical activities in hot and humid environment. Utilizing the large-scale manufacturing process developed in Phase I, ongoing research efforts will focus on the implementation of the technology on a broad range of fabric materials (e.g. polyester/polyurethane blends, cotton). As well, scientists at ATACAMA will optimize designs of the fluidic channels based on body sweat mapping research and will further enhance the robustness of the fluidic network. A series of breakthrough textile products (e.g. fabrics and apparel) integrated with optimized and robust 3D microfluidic-enabled moisture management technology will result from the completion of Phase II.

这个小型企业创新研究（SBIR）第二阶段项目的更广泛的影响/商业潜力是提高人们的舒适度，例如运动员在高强度训练和比赛中，在炎热和潮湿的环境中需要防护服的仓库工人，以及必须忍受极端工作条件的安全人员（例如消防员和急救人员）和军事人员。 我们革命性的水分管理技术利用新颖的3D微流体传输原理，将汗液从皮肤转移到衣服外面，在那里它可以滴走或被控制。与传统的基于毛细吸收的吸湿产品相比，我们的技术使织物和服装产品保持轻盈、始终干燥、高度透气和永不饱和。 阿塔卡玛？的技术旨在为佩戴者提供更好的体温调节和高强度活动期间的舒适度，有助于性能和安全性。该项目旨在解决目前水分管理产品在处理大量水分（例如汗液）时不足的问题。在高汗或高热的情况下，服装可能会迅速被水分饱和，导致潮湿、沉重、粘稠的感觉，这会影响穿着者的表现。我们拟议的研究旨在开发一系列能够持续输送水分的纺织品，使织物在炎热潮湿环境中进行高强度体力活动时保持干燥、透气和轻便。利用第一阶段开发的大规模制造工艺，正在进行的研究工作将集中在广泛的织物材料（例如聚酯/聚氨酯混合物，棉花）上实施该技术。此外，ATACAMA的科学家将根据人体汗液映射研究优化流体通道的设计，并进一步增强流体网络的鲁棒性。第二阶段的完成将带来一系列突破性的纺织产品（如织物和服装），这些产品集成了优化和强大的3D微流体水分管理技术。
