Symposium SF04-Development and Design of Responsive Architected Materials

Architected materials have garnered increasing attention from researchers across diverse scientific fields due to their superior and sometimes counterintuitive effective properties and macroscale performance stemming from a cleverly designed internal architecture. Advancements in additive manufacturing (e.g., improved resolution, material property selection, multi-material composition) have made possible the realization of the complex geometries across multiple length scales, which enables rational design of architected materials to achieve enhanced properties and novel functionalities. In addition, the properties and behaviors of architected materials do not have to be stagnant after their fabrication; a temporal degree of freedom can be encoded into the architectural design such that they can evolve in time. In response to various forms of stimuli (e.g., mechanical deformation, temperature changes, electromagnetic fields, acoustic wave), architected materials could attain different mechanical properties or chemical reactivity, release cargo via structural changes, or undergo controlled and deterministic failure. This built-in responsiveness could enable novel functionalities in intelligent matter that reacts, deploys, and evolves in specific environments or conditions directly at the material level, in ways similar to how living matter interacts with the surrounding environment. Furthermore, a system-level integration of sensing, computation, and communication functions with these programmable materials will enable materials intelligence guided by data-driven methods. The Development and Design of Responsive Architected Materials Symposium will gather prominent researchers in the area of architected materials to discuss topics related to their design, physics, and applications, including but not limited to bio-inspired and multi-functional design, harnessing of instabilities, dynamic mechanical responses, methods of activation, modulation and automation, and a wide range of potential applications (e.g., energy harvesting, signal transmission, robotics, wearable and implantable medical devices, analytical chemistry, etc.).
