Mechanical Computing with Continuum Morphing of Kirigami Shells

Continuum shape-morphing structures capable of encoding memory and performing logic operations have sparked tremendous interest in developing soft robots with embedded intelligence. Integrating memory and computing in such systems requires building blocks with a range of adjustable, metastable states. Previous efforts focused on creating mechanical memory and logic by exploiting snap-through instabilities in multistable structures, with each logic gate requiring a distinct structural design. This study introduces an innovative design approach using a single kirigami architecture to execute and switch between multiple fundamental logic operations. By leveraging the kirigami architecture as a foundational element, the study demonstrates mechanical signal transmission and performs half-adder computations. This strategy suggests broad applicability across diverse materials and structures, potentially simplifying the development of intelligent materials systems.
