The technology features a composite material system engineered for efficient moisture management in prosthetic liner applications. A thin (<1 mm) hydrogel layer, formed as a dual network or nanocomposite with high tensile strength and elongation, serves as a selective pathway for liquid water. This layer is paired with an optional intermediate layer that enhances viscous flow and an outer porous elastomer or open-cell foam that actively facilitates moisture escape. The design incorporates precisely engineered pore geometries and integrated wicking and cushioning elements, while a network of manufacturing methods—including sequential UV curing—ensures the optimal arrangement of monomers, crosslinkers, and reinforcing agents.
Description
This approach stands apart due to its multilayer integration and active moisture transport mechanism. Unlike traditional liners that trap moisture against the skin, this system uses a vacuum-induced pressure gradient to draw fluids away, reducing discomfort and potential skin issues. Its advanced material composition and precise structural design provide a unique balance of moisture permeability, durability, and gentle cushioning, offering a differentiated solution that effectively addresses common challenges in prosthetic applications.
Applications
Prosthetic liner moisture control
Orthotic liner moisture control
Moisture-wicking clothing
Spacesuit moisture control
Environmental suit moisture control
Advantages
Improved comfort and skin health by actively managing and removing moisture, reducing skin maceration and infection risks.
Efficient moisture removal through a multi-layer composite that channels water away from the limb using a low-vacuum pressure gradient.
Enhanced material durability and flexibility with advanced, thin dual network or nanocomposite hydrogels that maintain high tensile strength and elongation.
Maintains an airtight seal while allowing liquid water to pass through, offering a superior alternative to conventional silicone liners.
Versatile design readily applicable to prosthetics, orthotics, and other wearables like spacesuits and environmental suits.
