A human-machine interface based on single channel EOG and patchable sensor.

•A flexible dry electrode was manufactured to acquire the bioelectrical signals.•A new control paradigm and an efficient classification algorithm were combined to implement the HMI system.•An EOG-based HMI system was realized to recognize three kinds of eye movements with high accuracy and ITR.•This study combined the advantages of dry electrode and single recording channel to reduce the system preparation time and improve user comfort.
