Abstract
We present a programmable liquid matter which can dynamically transform its 2D shape into a variety of forms and present unique organic animations based on spatio-temporally controlled electric fields. We deployed a EGaIn (Gallium indium eutectic alloy) liquid metal as our smart liquid material since it features a superior electric conductivity in spite of a liquid state and presents a high dynamic range of surface tension and 2D area controlled by applied voltage strength and polarity. Our proposed liquid metal shape and motion control algorithms with dynamically patterned electric fields realize path tracing organic animation. We demonstrate an interactive 7x7 electrode array control system with a computer vision based GUI system to enable novice users to physically draw alphabet letters and 2D shapes by unique animatronics of liquid metals.
