Advancing Mechanical Computing: Modular Design and Multi‐Dimensional Signal Transmission

Abstract Mechanical computing, while not poised to replace electronic computing, presents a complementary solution in areas where electronic systems face challenges like high power consumption and environmental vulnerability. Despite the inherent limitations of mechanical systems in speed, size, and functional scalability, their unique 2D and 3D geometries offer multi‐dimensional signal transmission and non‐volatile logic computing, potentially enhancing computational density. However, a lack of advanced modular design strategies for complex systems has hindered progress in mechanical computing. This study introduces a top‐down design approach to non‐volatile logic mechanical computing using multi‐output logic gates designed with square lattices and bistable beams, addressing functional scalability through a modular design that facilitates the assembly of mechanical circuits. This innovation not only enhances computational density but also reduces system size, offering new avenues for research in fields like soft robotics and active metamaterials, and setting the stage for advances in mechanical computing systems.
