Problem

In the U.S., it is estimated that one in every 190 people have suffered from limb loss. [1] This shows the importance and opportunity of prosthetics. For all these people, their old functions can be regained with the use of a prosthetic limb.

USE

USE: It is important to look at the user aspects of wrist prostheses. For this there will be looked at the end users, society and enterprise.

Users: The users of a hand prothesis will be people who have somehow lost their hand or arm entirely. Their current way of living would be improved by giving them the possibility to use their prosthesis to pick up objects, which would also help them with basic uses of the hand. Further development could lead to even more possibilities such as catching objects or typing. This would greatly improve the quality of life for these people.

The preferences of the users would of course be a full-fuctioning arm and hand with perhaps even additional functions. The question is whether or not this is desirable, since if a prosthetic hand is more useful than u human one it could incentivise people to have a prostetic hand even if their current hand is still functioning.

Society: A hand prothesis will allow people who lose their arm or hand to more easily rehabilitate to their normal lives and jobs.

Enterprise: The enterprise will be able to sell prostheses.

Deliverables

The results of this project will be presented in the form of a 3D Functional Model (FuMo) together with an algorithm. The model will consist of a design for a prosthetic hand and wrist in a 3D environment (Probably NX10). Since the design will be virtual as of now, the two deliverables cannot be combined to give a single result. However the algorithm's functionality will still be proven in another way. If in the next couple weeks it is concluded that a physical model is possible to make within the given time frame, the option will be considered.
