The Amputee Coalition estimates that there are 185,000 new lower-limb amputees every year. To restore mobility, these amputees are fitted with an artificial limb, and the interface between the remainder of the limb and the artificial limb is a medical device called the socket. For the artificial limb to work in harmony with the user, the quality of the limb-socket fit is critical. A proper fit greatly reduces the risk of blisters or infections that ultimately injure the amputee and reduce their ability to continue using the prosthetic limb. The team is developing a reusable, in-socket sensor array to help clinicians obtain accurate feedback to provide a quality, comfortable fit for patients.
