- I study the relationships between structure- properties-function in a variety of biological materials mainly chitin-based cuticular materials from arthropods, but also mineralized structures such as the sea urchin test and spines. We want to understand how they operate but also how they form. The exoskeleton of arthropod, the cuticle, is intrinsically multifunctional as it has to serve both as a skin and a skeleton and as it carries a diverse set of tools and a myriad of sensors. We are fascinated by this inherent multifunctionality that is enabled by an incredible versatility in materials architecture and properties. This material versatility is indeed thought central to the evolution of the more than million species that render Arthropoda the largest, most diverse, animal group. It is also what makes the arthropod’s cuticle an especially attractive archetype for bio-inspired multifunctional materials design. After years of research in biomimicry it is clear that solutions from nature cannot simply be copied into engineering. Instead, an in-depth understanding of the “design” principles as used by biology within the context of their evolutionary path and the complementary mechanistic understanding on how these structures are synthesized and organized hold promise for bio-inspired design.
