Abstract

Myoelectric prosthesis is considered as a powerful solution in solving daily life issues with upper limb amputations, since they're backed by Electromyographic technology which turns muscular activity signals into functional movements. However, picking up these signals requires electrodes attached to the surface corresponding muscles. This presents a lot of problems such as slipping and discomfort, further making positioning the sensors harder. This paper aims to design an adaptive myoelectric prosthesis, specifically dedicated for writing capable to generate handwriting from recorded forearm muscles activities using surface electrodes. It also conserves good signal quality through firm but comfortable and customizable binding to fit the amputated forearm. The proposed Myoelectric prosthesis design allows an intuitive and smooth control of the writing movement while keeping an aesthetic, human-like look.
