A feature extraction issue for myoelectric control based on wearable EMG sensors

With recent advancements in wearable sensors, wireless communication and embedded computing technologies, wearable EMG armbands are now commercially available and accessible to most laboratories. Due to the embedded system constraints, however, these armbands typically sample EMG signals at a lower frequency (e.g. 200 Hz for the Myo armband) than professional versions. It remains unclear whether existing EMG feature extraction methods, which...
