Recent advances in data-driven and interconnected manufacturing have the potential to revolutionize the design and processing of multifunctional elements with unprecedented precision and heterogeneity. These elements include architectured metamaterials with integrated functions that are highly desirable for a broad range of applications in confined spaces, such as impact absorption, thermal management and chemical processing, optical transparency, structural morphing, and real-time monitoring and repair. To fully realize the potential of these multifunctional elements, an integrated knowledge base is crucial for setting up, steering, and analyzing their functionality. This requires combining different geometries and choices of digital voxels with domain-specific design constraints, as well as a library of accurate designer voxels with predictive analytics that capture essential mechanical and physical properties based on the microstructure.
In this seminar, we will explore the three-dimensional microfabrication techniques and expertise required to design and fabricate these architectured metamaterials for combined functions, including energy absorption, actuation/morphing, and micro-scale bioreactors for tissue engineering. I will also discuss our effort on selective ion doping of oxide electrolytes with electronegative metals, which shows promise for reproducible resistive switching that is critical for reliable hardware neuromorphic circuits.
