Abstract

A nonlinearly organized framework made of soft materials was studied. The framework is self-responsive, pluripotent, yet reversible for wetting on various topographic surfaces due to the unprecedented hierarchy within the framework. We show that nonlinear frameworks could offer practical routes for on-site diagnosis and therapy in future medical devices that require conformal wettability by overcoming the limitations of nonstructured films. From the presented hierarchical cuts, pluripotency against cell-scale textures was achieved with proper flexural rigidity to handle them reversibly. We thoroughly investigated the theoretical models by considering all geometric parameters in each thickness level one organized in tandem. The nonlinearity from hierarchical cuts demonstrated here helps to overcome the inherent conflicting characters of the solid, that is self-wettability versus mechanical stability.
