Amphidynamic crystals are a promising platform for the design of artificial molecular machines that rely on thermal activation of rapidly moving molecular elements in a lattice. The conversion of thermal energy into mechanical work at the macroscopic scale is an emergent property that could enable the design of all-organic artificial muscles in soft robotics. The thermosalient effect is a visually observable motion of crystals that occurs due to a sudden release of strain accumulated in the crystal lattice over a phase transition. The rapid switching of the entire crystal structure occurs on time scales that are several orders of magnitude faster than those of common phase transitions, resulting in self-actuation of the crystals. An amphidynamic thermosalient crystal that is capable of molecular and macroscopic motion is a precedent of being dynamic at two levels of structural hierarchy and provides insights into the relationship between the underlying molecular and lattice dynamics.
