My first idea for the Final Project


protesi



The medical 3D printing sector is growing rapidly. Many prostheses are produced, but they often look very different from the limb they are replacing.
My goal is to create a prosthesis that is functional but as close to the skin as possible.
I would like it to be made of a soft material that can be adapted to the patient's body temperature and that is the same colour as the complexion of the wearer.
For example, I personally don't like prosthetics in colors like blue or red.
If the arm is more or less pink or brown (depending on nationality), why does the prosthesis have to be blue?
Why is the prosthetic hand often much larger than natural and subjective proportions?
Why is it necessary to notice that it is a prosthesis?
Obviously these are accessory characteristics that I hope to satisfy. First of all I will have to focus on functionality!
Specifically: I would like to develop an intelligent arm.
The hand must be able to grasp objects and in the fingertips and I would like to put sensors able to measure the pressure to be exerted (less if the object is delicate).

My benchmark

I have done a lot of research to realize what kind of 3D prosthesis have been developed so far.
What I wish I could avoid is this type of aesthetics
My ideal model is this which has actuators for individual fingers control, adaptive grip, force feedback, and also a custom skin tone!
Another amazing project is this: a polyarticulated prosthetic hand with myo-electric control that can return more than 90% of the lost functionalities.
To conclude: I also found these materials very interesting to better understand the meaning of myoelectric signal.

Final Project

New Idea

In these months I have thought over my final project and decided to abandon my initial idea. I thought of a game for children to make a very simple (but equally boring) physiotherapy exercise: the simple, but fair, distribution of weight on the foot. Many people distribute it badly and hardly aware of it, especially children. They also often don't even like to do rehabilitation exercises. So I decided to model a foot on OnShape taking care to create the space in which to insert a strip of neopixel with three rgb leds (one that will be in the front part of the foot, one in the middle and one in the back).
