Design of multi-channel wireless array wearable surface electromyography testing equipment

Abstract

Since there are few researches on multi-channel surface electromyography (EMG) devices, this paper presents a new design scheme. The system uses highly integrated chips and designs a new wearable electrode array. Also, the data is transmitted by wireless WiFi with a high bandwidth. Scalable modular architecture is also applied to make the system suitable for different scenarios. Through experimental tests, the device can work for more than 5 hours, effectively collecting the EMG signals generated when the hand muscles move.
