Meta-biomaterials

Abstract

This talk examines meta-biomaterials, which are engineered materials that achieve extraordinary physical and biological capabilities through their specific internal structures and surface treatments. By precisely controlling the geometry and topology of these materials at the microscopic level, scientists can dictate how they behave at a larger scale. The work explores several dimensions of this design process across multiple size regimes. At the macroscale, the focus remains on creating personalized medical implants and adaptable devices such as metallic clay. Moving to the microscale, the study investigates how multi-material additive manufacturing and auxetic structures influence cellular behavior through specific curvatures. Furthermore, nanoscale analysis examines how surface textures can enhance bone growth, modulate immune responses, and eliminate harmful bacteria. To unify these various scales into a single functional unit, the research employs origami and kirigami techniques, along with 4D printing, to develop self-folding, shape-shifting materials that can even incorporate flexible electronic components for advanced biomedical monitoring or therapy.
