Color, as perceived through the eye, transcends mere information in the visible range of electromagnetism and serves as an agent for communication and entertainment. Mechanochromic systems have thus far only aimed at satisfying the sense of vision and have overlooked the possibility of generating acoustic vibrations in concert with their visual color responses. Transcending the boundaries of the two senses, we herein elucidate a strategy for their concurrent and synesthetic fulfillment by electrically actuating an organogel photonic device, controlled by a single input signal. This new class of devices is materialized from a photonic crystal layer with an organogel matrix. Exploiting a dielectric elastomer actuator, the system’s mechanical response permits the exploration of visible-light reflection alongside audible sound wave generation, thereby making it amenable to modulate sound and color simultaneously yet independently.
