Abstract

Abstract:

A novel classifier is presented in this paper. It can achieve the finger motion real-time control of a 3-DOF prosthetic hand by measuring the surface electromyography (EMG) signals. The signals are measured by three electrodes which are mounted on the flexor pollicis longus, flexor digitorum profundus and extensor digitorum. The methods of autoregressive (AR) model and sample entropy are used to construct the feature vectors for the classifier.

Key words: pattern , recognition, , EMG , control, , RP, , AR , model, , sample , entropy
