Real Time Prosthetic Hand

Abstract

Electromyography (EMG) is a biomedical signal which is recorded from muscle. It can detect muscle movements. By using HMI (human machine interfacing), EMG can be used to control prosthetic arms by an amputee individual.

A 3D printable design for a myoelectric prosthetic arm is presented. The arm is actuated and controlled by a user flexing his/her muscles. The bionic arm presented has the potential to be used by an amputee or person born without a limb. This type of technology does exist although it is expensive and generally not available to people in developing countries.

Rapid growth and advancement of the 3D printing industry allows individuals to become small scale producers. Advancements in 3D printed prosthetic arm are attached to victims during war throughout North Africa. These devices are purely mechanical and less complex compare to myoelectric devices. We can see that 3D printed devices have the potential to positively impact people’s lives. 3D printing does have its limitations but growth and development will lead to upgradation during time.
