prosthetic arm rejection rates can be as high as 80%

How can we change that?

User experience research

This prosthetic socket is designed for Mr. Pinon, a patient with a transhumeral amputation. He wanted a socket that would allow him to do tasks like mowing the lawn or using tools and keep his arm stable without squeezing very hard and cutting off circulation.

Testing out pressure points

Electroactive Polymer :
material that contracts when in contact with an electrical current

Parts of the socket could be made out of electroactive polymer that contracts when the arm is in a downward position to keep the prosthetic from fallling off, and loosens slightly when the arm is in a more vertical position.
