Adaptive Pressure Prosthetic Socket (APPS)

 

Abstract
This project aims to create a universal adaptive prosthetic socket with variable pressure based on force feedback and to provide an alternative to traditional suction-fit prosthetic arm sockets by increasing both comfort and efficacy in performing activities of daily living (ADL’s). It incorporates a combination of a positive pneumatic pressure bladder and granular jamming technology to provide an adaptive lining within the socket which enables it to adapt to the ever-changing shape of the limb, as well as vary the pressure it exerts in order to maintain grip on the limb even through intense motions such as heavy lifting. Community Benefit: This combination of technologies will improve ADL efficacy and reduce prosthetic slippage and discomfort when lifting heavy objects, which could help decrease amputee prosthetic rejection rate. In addition, this project could improve the efficiency of the prosthetic fabrication and fitting process, which could help increase the accessibility of prosthetics to more people.
