What is A Reprogrammable Mechanical Metamaterial with Stable Memory about?
Metamaterials are designed to realize exotic physical properties through the geometric arrangement of their underlying structural layout. Traditional mechanical metamaterials achieve functionalities such as a target Poisson's ratio or shape transformation through unit-cell optimization, often with spatial heterogeneity. These functionalities are programmed into the layout of the metamaterial in a way that cannot be altered. Although recent efforts have produced means of tuning such properties post-fabrication, they have not demonstrated mechanical reprogrammability analogous to that of digital devices, such as hard disk drives, in which each unit can be written to or read from in real time as required. Here we overcome this challenge by using a design framework for a tileable mechanical metamaterial with stable memory at the unit-cell level. Our design comprises an array of physical binary elements (m-bits), analogous to digital bits, with clearly delineated writing and reading phases. Each m-bit can be independently and reversibly switched between two stable states (acting as memory) using magnetic actuation to move between the equilibria of a bistable shell. Under deformation, ea
