Scales are rooted in soft tissues, and are regenerated by specialized cells. The realization of dynamic synthetic analogues with inorganic materials has been a significant challenge, because the abiological regeneration sites that could yield deterministic growth behavior are hard to form. Here we have overcome this fundamental hurdle by constructing a mutable and deformable array of three-dimensional calcite heterostructures that are partially locked in silicone. Individual calcite crystals exhibit asymmetrical dumbbell shapes and are prepared by a parallel tectonic approach under ambient conditions. The silicone matrix immobilizes the epitaxial nucleation sites through self templated cavities, which enables symmetry breaking in reaction dynamics and scalable manipulation of the mineral ensembles. With this new platform, we devised several mineral-enabled dynamic surfaces and interfaces. For example, we showed that the induced growth of minerals yielded localized inorganic adhesion for biological tissue and reversible focal encapsulation for sensitive components in flexible electronics.
