| Abstract Scope |
Over millions of years of evolution, biological soft fibrous tissues have developed intricate structural mechanisms that enable exceptional mechanical performance, especially in enduring large deformations. These tissues are composite materials of repeating building blocks with diverse structural motifs, such as fiber fraction, orientation, hierarchy, crimping, and weak interfaces. We have developed new biomimetic composite materials by combining natural fibers with hydrogels using weak and reversible interfaces. We reverse-engineered different structural motifs to create a toolbox that reveals the isolated effect of these motifs. Our materials display hyperelastic and anisotropic behaviors, with large deformations together with multifunctionality and morphing abilities. Furthermore, by manipulating these motifs, we've successfully customized a wide range of mechanical behaviors like various functional tissue structures. Through reverse biomimetics, we can gain a deeper understanding of the intricate structure-function interplay in fibrous soft tissues. This knowledge will aid in designing next-generation materials for future soft-tissue repair and replacement. |
