After watching the TED talk [] given by Aimee Mullins about her 12 pairs of legs, I had an “ah-ha” moment: materials sensibility has a direct application to prosthetics. Not only do prosthetics have a functional aspect to their reason for existing but they also have intangible functions. Just think of the implications of their use – perception, intention and aesthetics – affects the emotional well being of the people they serve. The design of prosthetics, the design of their intangible characteristics can go a long way to enhance a person’s life.
