Supramolecular assemblies are promising building blocks for the fabrication of functional soft devices for high‐tech applications. However, there is a lack of effective methods for large‐scale manipulation and integration of nano‐sized supramolecular structures on soft substrate. Now, functional soft devices composed of micellar filaments and hydrogels can be created through a versatile approach involving guided dewetting, transfer‐printing, and laser‐assisted patterning. Such an approach enables unprecedented control over the location and alignment of the micellar filaments on hydrogel substrates. As examples, freely suspended micellar fishnets immobilized on hydrogels are formed, showing the capability of trapping and releasing micro‐objects and the piconewton force sensitivity. By incorporating responsive moieties into hydrogels, shape‐morphing actuators with micelle‐controlled rolling directionality are constructed.
