This technology is a humidity-responsive smart textile that dynamically adjusts fabric breathability through reversible hygromorphing actuation, improving moisture and thermal comfort in clothing.
Current approaches to moisture and thermal management in clothing rely on passive materials, coatings, or fabric vents that provide fixed levels of breathability and cannot adapt to changing environmental conditions or varying physical activities. As a result, garments often trap moisture in humid conditions or allow excessive heat and moisture loss in dry environments, leading to discomfort, reduced performance, and potential safety concerns. Existing textile solutions have been limited due to poor durability or incompatibility with common fabric processing and care methods. Addressing these limitations is necessary to enable garments that dynamically regulate moisture and thermal comfort across diverse conditions without sacrificing user wearability or product durability.
This technology describes a fabric that incorporates a moisture-responsive composite layer that mechanically responds to changes in environmental humidity. Variations in humidity induce reversible deformation within this layer, which translates into controlled bending or opening of fabric features that modulate air and water-vapor flow through the textile. By integrating this responsive layer as part of a fabric bilayer, the resulting material passively adjusts its permeability without requiring external power or user input. The extent and direction of the shape change can be controlled through material composition and geometric design, allowing for different venting behaviors within a garment.
