In this study, we propose a compact drive mechanism that replicates the dynamic movements of the human eye—such as natural eye opening and closing and blinking with a cycle time of approximately 300 ms—within conventional maxillofacial prostheses. The movement of the other healthy eye is detected via electrooculogram (EOG) measurements, and the detected signals are used to drive a mechanism comprising a solenoid, spring, and ratchet mechanism, thereby enabling blinking at the same speed as the healthy eye and maintaining eye opening and closing.
