Abstract Mechanical metamaterials have considerable application potential, but are often limited to single applications owing material and manufacturing constraints. To achieve a “single structure, multiple applications” goal, this study presents multifunctional metamaterial structure. The cells gain significant deformation recovery abilities by incorporating the concept of tensegrity structure balance flexibility rigidity using rigid‐flexible fabrication process. Inspired cat‐tongue barbs Hooke's law, an innovative pre‐stress programming is designed for integrated fabrication, enabling multilevel control each cell. This programmable stress allows twin‐cell array transition in situ from monostable bistable states provides critical‐force functions states. After assembling nine‐cell array, offers wide range adjustable stiffness levels, soft‐rigid transitions varied force‐displacement responses without need additional tools. It also controlled collapse ratios through control. Additionally, features isotropy with Poisson ratio v = −1 clear indentation resistance. approach promising such as energy dissipators, automotive equipment, passive safety. Metamaterial produced via concept. Using barb‐shaped locking structures adjust elastomer length ( x n ). Modulating adjacent achieves multistability adjustability. controllable resistance, variable response, stiffness, deformation.

Abstract Ionic hydrogels are uniquely suited as force‐sensing layers because of their good biocompatibility and controlled electromechanical properties. The emerging piezoionic effect allows them to sense the position pressure, but low response rate limits applications. Herein, this work focuses on modulating time outputs through crosslinking. underlying mechanism is investigated perspective deformation recovery ion migration behavior in ionic hydrogels. As a result, developed sensors capable distinguishing static forces range 0.1–5 s while monitoring dynamic force, breaking limitations conventional self‐powered pressure that have trouble tracking forces. Furthermore, by utilizing convert touch indentation into transverse gradient potential, constructed achieve accurate finger pressing sliding trajectory. proof‐of‐concept, pattern unlocking security authentication successfully validated based sensors. This design strategy tactile sensor crosslinking expected provide fresh path for large‐scale flexible human‐machine interfaces.
