Research on EMG-based Classification of Hand Movements using Four Electrodes Arrangements on Forearm

Although various types of myoelectric prosthetic hands using surface electromyogram have been developed, the placement electrodes to acquire potential needs be adjusted by a specialist, and differs from individual individuals, so it user. Also, is not covered health insurance in Japan, there are technical fees for product price initial setup. We propose method electrode pretreatment that does require much expertise placing at mid-forearm form wristband improve them. In this study, we report effects muscle measurements on pattern discriminator estimation useful measurement points fixing four arranged wristbands. proposed method, accuracy identification more than 95 %.
