Adaptability is one of the hallmarks of living systems that provide resilience to survive and flourish in a dynamically changing environment. Nature produces outstanding materials for structural applications, which can adapt to their surrounding environment. For instance, bone regulates mineral quantity proportional to the amount of stress. It becomes stronger in locations subjected to higher mechanical loads. This capability leads to the formation of mechanically efficient structures for optimal biomechanical and energy-efficient performance. Inspired by bone, I will present composites that trigger proportional mineral deposition from electrolytes on piezoelectric matrices upon mechanical loadings so that it can self-adapt to mechanical loadings. I will present our approach and resulting material properties. I will also present our approach for reprogrammable self-configurable structures based on the material by controlling the modulus distribution through the applied loading.
