摘要：
Kinetic matter-any material system capable of movement and deformation-represents a major frontier in materials science. By embedding autonomy enabled bythe synergistic coupling between mechanics and electrohnics, autonomous kineticmatter eliminates complex hardware architectures, offering more efficient, robust, andscalable solutions for soft robotics and adaptive structures. This talk explores howgeometry, instability, and physical learning can be harnessed to design these intelligentsystems. First, we introduce a geometric design framework based on the discretetransformation method to achieve desired displacement fields invariant to configurationremapping. Second, we demonstrate how material-level instabilities can be channeled,showcasing a self-oscillating wire enabled by asymmetric Willis viscosity, that can alsointeract with a string network to realize various wave modes. Finally, we present twotypes of physical learning machines that utilize contrastive learning to achieve targetedstiffness tensors and vibration modes, paving the way for materials that adaptively thinkthrough their own physics.
