Design & Analysis of Prosthetic Hand with EMG Technology in 3-D Printing Machine

Abstract

Prosthesis is an artificial extension that replaces a missing body part. Prostheses are typically used to replace parts lost by injury or missing from birth or to supplement defective body parts. One of the main requirements of artificial arm is that functionally, it should be as near to the natural hand as possible. Various designs of artificial arm are available in the market, categorized as mechanical, electrical and Electro-Mechanical. Myo-Electric arm is stimulated by muscle signal available from the stump of amputee. In this method the EMG signals are picked from the surface and the time domain features associated with the intended motion are extracted using suitable technique. The Goal behind this project is low-cost objective was achieved by developing an inexpensive EMG control platform Prosthetic hand that is designed to be produced inexpensively on a 3D printer. This EMG Technology Prosthetic hand User Interface also reduces the chance of a stray muscle impulse causing unintended actuation of the hand and reducing the mental task load for the user of the device. In this project first prepare a design in solid works with proper dimensions and then converted into Three Dimensional Object, after complete the entire design then the design can be adopted in to 3D Printer, it will take few hours of time to prepare the final object. Once we compare the current prosthetic hand with this advanced EMG prosthetic hand cost is drastically decreased and user can feel very comfortable to wear this because of less weight and EMG Sensor technology.
