In the last weeks I though in the design of a prosthetics , analizing the some examples of modelling of robotic arms, I have some though about the design of the prosthetics:
1. I wanted to design a device that i can implemet for a person , functionla in the mechanical and the lectronical part as posible
2. I want to combine diferent materilas in order to get insigde to wearable electronics, implemeting some sensor and actuators for Ex: Nithinol memory wire, those have a fine interaction and apparience, as the human movements.
3. I can be on the feed of the person who has the problem . in fact I can simulate and appropiate the problems thinking in the expereimentation of the mecanical issues.
PLAN : design a orthotics that help the person to have a right posture of the hand , and controlling the movements fo the finger , mit help of the 2 diferent imputs :
lecture of the MYO signals: which help to recognize the movements of the muscles,
lectrure of the ROW cordinates,correcting the position of the hand.
Output use of the SMA wire increasing the power and enable the movement of the hand#
MANUFACTURE AND MATERIALS:
Orthoses were traditionally made by following a tracing of the extremity with measurements to assist in creating a well-fitted device. Subsequently, the advent of plastics as a material of choice for construction necessitated the idea of creating a plaster of Paris mold of the body part in question. This method is still extensively used throughout the industry. Currently, CAD/CAM, CNC machines and 3D printing[2] are involved in orthotic manufacture.
Orthoses are made from various types of materials including thermoplastics, carbon fibre, metals, elastic, EVA, fabric or a combination of similar materials. Some designs may be purchased at a local retailer; others are more specific and require a prescription from a physician, who will fit the orthosis according to the patient's requirements. Over-the-counter braces are basic and available in multiple sizes. They are generally slid on or strapped on with Velcro, and are held tightly in place. One of the purposes of these braces is injury protection.[3]
