I designed custom prosthetic sockets 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. We use a 3D printer to create a multi-material prosthetic socket which relieves pressure where needed on the anatomy of the patient. In short, we're using data to make novel sockets quickly and cheaply. In a recent trial we just wrapped up at the Media Lab, one of our patients, a US veteran who has been an amputee for about 20 years and worn dozens of legs, said of one of our printed parts, 'It's so soft, it's like walking on pillows.' (Laughter) Disability in our age should not prevent anyone from living meaningful lives. My hope and desire is that the tools and processes we develop in our research group can be used to bring highly functional prostheses to those who need them. For me, a place to begin healing the souls of those affected by war and disease.
