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.

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.
