The prosthetic socket is the part in which the amputee inserts their residual limb, and which connects to the prosthetic ankle. Even in the developed world, it takes a period of three weeks to often years for a patient to get a comfortable socket, if ever. Prosthetics still use conventional processes like moulding and casting to create single-material prosthetic sockets. Such sockets often leave intolerable amounts of pressure on the limbs of the patient, leaving them with pressure sores and blisters. It does not matter how powerful your prosthetic ankle is. If your prosthetic socket is uncomfortable, you will not use your leg, and that is just simply unacceptable in our age. So one day, when I met Professor Hugh Herr about two and a half years ago, and he asked me if I knew how to solve this problem, I said, 'No, not yet, but I would love to figure it out.' And so, for my PhD. at the MIT Media Lab, I designed custom prosthetic sockets quickly and cheaply that are more comfortable than conventional prostheses. I used magnetic resonance imaging to capture the actual shape of the patient's anatomy, then use finite element modelling to better predict the internal stresses and strains on the normal forces, and then create a prosthetic socket for manufacture.
