DEyeA: Artificial Muscles for the Restoration of Eye Blinking Following Facial Paralysis

Yves Perriard, Yoan René Cyrille Civet, Stefania Maria Aliki Konstantinidi, Amine Benouhiba

Facial nerve palsy results in the inability to control facial muscles, including the Orbicularis Oculi, which is the main muscle enabling the blinking action. Blinking is not only important for responding socially to other humans, it is also essential for ...
