Abstract
A triangular shaped liquid crystal network is shown to undergo a continual, rocking chair-like oscillatory chaotic motion upon exposure to a surface of constant temperature. With the addition of an azobenzene chromophore, dual response is achieved, extending the actuation freedom towards a film that shows rocking and rolling motion.
