Embedding information processing into mechanical metamaterials is conducive to constructing multifunctional mechanical systems, which have unique advantages to provide information processing platforms in extreme environments. However, achieving high-density, reprogrammable, and visually readable information processing in most mechanical metamaterials remains a challenge. Here, we report a multi-bit programming spine structure strategy to create a magnetorheological metamaterial with high-density, reprogrammable, and visually readable information encoding capacities. Inspired by spine features, the magnetorheological spine beams, exhibiting substantial stiffness variation by bi-stable transition, are meticulously conceived as the stiffness reprogrammable magnetorheological metamaterial (SRMM). The SRMM exhibits a large stiffness conversion capability (40-fold) and high-density information encoding performance (10-bit). Coupling with the mechanoluminescent materials, the mechanical inform..., , # Stiffness reprogrammable magnetorheological metamaterials inspired by the spine for multi-bit visual mechanical information processing

## Description of the data and file structure
The original data of all the experiments in the manuscript are provided outside. The tensile and compression performance of printed films and structures was obtained by a dynamic mechanical analyzer (DMA, ElectroForce 3200, TA Instruments, USA) and a universal tensile instrument (Criterion⢠Model 43, MTS Co., LTD, China) with a 500 N force sensor module. The loading rate was set at 0.1 mm/s.
