Active elastic solids
Active solids are elastic structures made of, or doped with active units. They are particularly relevant when studying dense biological systems, like confined cell monolayers, dense bacterial suspensions, bacterial biofilms, and dense pedestrian crowds. We develop a minimal experimental realization of an active solid by embedding self-propelled robots at the nodes of an elastic spring network. Moreover, we demonstrate the presence of a feedback between structural deformations and the orientation of active forces, which can give rise to fascinating self-oscillating dynamics called collective actuation.
