A 128-Channel Wireless Wearable Myolink (W2 Myolink): Functional Characteristics and Multidisciplinary Experiments
Abstract
<title>Abstract</title> <p>This paper presents Wireless Wearable Myolink (W2 Myolink), a high-density, battery-powered system for wireless acquisition of surface electromyography(EMG) signals, and demonstrates its practicality across diverse experimentalparadigms. The device features a compact form factor (110x70x35 mm), low weight(160 g), and continuous operation for up to 6 h. It supports low-noise (1.34 µVRMS),high-resolution (24 bit) recordings from 128 EMG channels with real-time wireless datatransmission over Wi-Fi. The capabilities of W2 Myolink have been validated througha series of experiments. Conventional EMG studies included the recording and analysisof muscle activity during various gestures and hand movements, as well as concurrentEMG–EEG measurements for the investigation of cortico-muscular coherence. Thesystem’s suitability for clinical and pathological scenarios was examined using surrogateEMG signals representative of healthy subjects and of conditions such as myopathy,neuropathy, and Amyotrophic Lateral Sclerosis (ALS). More complex experimental usecases involved human–robot interaction with ISYBOT robotic arms, intraoperativeEMG monitoring during different types of surgery with and without exoskeletonassistance for the surgeon, and EMG acquisition during psychedelic experiencesinduced by psilocybin. Collectively, these results demonstrate that W2 Myolink canreliably acquire and wirelessly transmit high-quality, high-density EMG data in a broadrange of research and application contexts.</p>
