Abstract—This paper describes the design of a novel non-invasive wearable device that acquires 128-channels array surface electromyogram (sEMG) in real-time. The device contains 8 individual microcontroller-based acquisition modules and a data fusion module. The acquisition modules share the same structure, and the data fusion module is an ARM-based platform running the Linux operating system. A 16-channel matrix-type (2×8) electrode array patch is used in each acquisition module to parallel acquire sEMG signals, which are digitalised by 2 ADCs. Every 100 ms, the sEMG from 8 acquisition modules are packed in the ARM controller and transferred to PC via WIFI. The sEMG signals are filtered with infinite impulse response recursive least-squares adaptive filter (IIR RLS) on PC.
