Inspired by the macro/microstructures of starfish and beetle elytra. a series of bio-inspired structures (BSs) with improved comprehensive mechanical performance were proposed and fabricated. In the BS design. the principle of the branching structure of starfish was borrowed and each arm was endowed with calcified exoskeletons that can bend autonomously. https://parisnaturalfoodes.shop/product-category/herbamare-sea-salt/
