Self-propelled ion gel shows autonomous motion on the water surface. When 50 ion gels are floated on the surface of water in a 65 mm diameter petri dish, each ion gel moves randomly in the initial state, but forms aggregates over time. In this study, all 50 ion gels in the system are tracked for 20 minutes and analyzed. The center-to-center distance between two adjacent ion gels in the aggregate fluctuate over time with an amplitude of up to 1.2 mm. This is consistent with the dynamics of the aggregate which repeatedly shrink and expand.
