Polyurethane may hold the key to a gripping future for prosthetic hands. Researchers at Missouri University of Science and Technology have been hard at work developing polyurethane aerogels – called shape memory polymers or SMPs. When bent, folded or twisted, the aerogels return to their original shape. They are even capable of bending on their own when a stimulus like heat is applied.
A Prosthetic Prototype
To demonstrate the possible application of the aerogel technology, researchers built a model of a prosthetic hand from the SMPs that was capable of mimicking coordinated muscle function. When heat was applied, the fingers...Electronics, Innovation Bonds
