Active Knit Compression Stockings
Shape memory alloy wires provide active compression
Active knit compression garments dynamically apply compression to various areas of the body for medical, athletic and aerospace applications. The technology uses knitted garments that integrate shape memory alloy (SMA) wires trained through an annealing process to remember a straight or slightly curved form. When heated, the SMA wires return to those trained forms to cause the knit to contract, providing active compression. The knitted garments can wrap around the body in the form of leg sleeves, arm sleeves or body wraps. The garments give the wearer dynamic control by providing variable levels of functional compression, which is determined by the properties of the SMA, knit stitch type, size and structure and temperature of the SMA knit.
Provides dynamic control over pressure exerted
Current compression garments include large, inflatable garments tethered to inflation sources or passive, elastic stockings that are not only difficult to put on/take off but do not apply controllable or dynamic pressures on the body. This new active knit compression technology combines the mobility and low-profile features of the passive knit compression stockings with the dynamic and controllable features of the inflatable garments. Using shape memory alloy materials trained to return to specific forms when heated, this technology is lightweight, low profile and provides dynamic control over the amount of pressure exerted.
Phase of Development
- Prototype developed.
- Low profile and controllable compression garment
- Dynamically applies therapeutic compression
