The Ember-Arm is an innovative prosthesis (developed in the 3D Printing and Visualization Center of Pécs University) that helps the major muscles of an amputated arm or hand to function and maintain their strength, furthermore to train the muscles and also to improve the quality of life of the subject. The objective of our mobile application is to enable the patient to use the prosthesis in the most effective way through self-practice. The process is powered by artificial intelligence, the upper limb prosthesis will learn the wearer’s common moves and gestures. The system stores this movement data and provides the doctor or the physiotherapist with continuous information.
