A remarkable feature of certain biological organisms is their ability to alter their shape and functionality in response to environmental cues. Polymer gels undergoing the Belousov-Zhabotinsky (BZ) reaction are unique self-oscillating materials that can be used to design a variety of soft materials with biomimetic functionality. We focus on chemically-mediated communication between multiple pieces of BZ gels. We show that the system exhibits autochemotaxis, which results in a spontaneous self-aggregation of the pieces.
