Design and Visualization of a Hierarchical Metamaterial with Tunable Stiffness.

ABSTRACT: Metamaterials with stiffness tunability have demonstrated great potential in mechanical systems that operate in variable environments. However, most existing stiffness-tunable metamaterials exhibit high-dimensional and nonlinear structure-property relationships, which hinder precise on-demand tuning and real-time stiffness visualization. Here, we present a reconfigurable hierarchical metamaterial that integrates stiffness tunability, linear structure-property relationship, and real-time self-sensing stiffness visualization into a unified platform. Kinematic analysis shows that the hierarchical metamaterial can be reconfigured through kinematic bifurcations into various single- and multi-level configurations with different numbers of active hinges, and maintain a single degree of freedom in
