This is an experimental design. It might not look good, but it can be refined. I'm not 100% sure this design is solving an existing problem, but in my opinion it might. The problem is the following: the users of prosthetic hands have no feedback if their fingers touched an object, or did not. In order to solve this problem, I incorporated a simple flexible tube, closed on both ends, running from the fingers to a custom wristband. If the fingers touch anything, then on the armband a small part inflates in proportion with the gripping strength, giving the user force feedback.The design can be changed to be more ergonomic (I lack the necessary anatomy knowledge to create a really nice prosthetic hand), and some parts are not designed yet, but they will be ready before the deadline. Hopefully I can print the hand this weekend, and try if it works.
