The aim of this proposal is to investigate the leading principles of dissipative self-assembly, in collections of self-assembled self-spinning motors
Abstract
Gears and cogwheels are fundamental components of macroscopic machines to channel power into desired motion. Their self-assembly and control is a key challenge along the path to feasible micromachines. In contrast to macroscopic devices, active cogwheels operate in the presence of thermal fluctuations, which call for new design principles. Unlike equilibrium phases of matter, which stem from the balance between entropy and internal energy, the organization of self-spinning motors states arise from the competition between active torques and interactions. We investigate the relationship between structure and synchronization of untethered active spinners or as building blocks of geared metamaterials. This proposal paves the way for the design of functional materials which macroscopic functionalities are encoded in microscopic building block, with a versatility and resilience formerly limited to the biological realm.
