Advances in actuating fabrics could enable a paradigm shift in the field of smart wearables by dynamically fitting themselves to the unique topography of the human body. Active fabrics and fitting mechanisms are described herein that enable garments to conform around surface concavities without requiring high elasticity or a multiplicity of closure devices. Advanced materials and systems innovations (1) enable novel garment manufacturing and application strategies, (2) facilitate topographical fitting (spatial actuation) through garment architectural design, and (3) provide tunable NiTi-based SMA actuation temperatures to enable actuation on the surface of human skin. Such fabrics and garments are usable in a variety of fields including medical compression, technical sportswear, exosuits, space suits and components thereof, or non-garment applications.

Topographically conforming garments

Yarns incorporating filaments of shape memory materials are described herein that enable the creation of fabrics, garments, and other materials with tunable force absorption or exertion capabilities, as well as creating complex shapes and structures upon actuation. Systems and methods described herein enable selective buckling, recruitment, compression, and other desirable phenomena by actuating fibers in knitted patterns, whether used as isolated filaments or in twisted yarns.

Multifunctional active yarns and textiles

Garments having active and passive knitted rows can provide desired levels of compression. Garments made of active and passive knitted rows can provide dynamic levels of compression with respect to both location and over time to address a variety of conditions.

Active knit compression garments, devices and related methods

Anchoring of fabrics for applications in which force is applied by or on the fabric facilitates new uses and functionalities. Dynamic anchoring through any of three modes (mechanical, compressive, or friction-based) enables transient or permanent anchoring across a garment or other fabric.

Dynamic anchoring using localized active compression

A device of a shape memory material configured to implement a predetermined level of expansion while allowing contraction and twist can be implemented in a portion of a vascular system, such as in the left ventricle of the heart of a patient suffering from heart failure with preserved ejection fraction.
