A pair of TCO cells’ capability to demonstrate mechanical memory storage. a Two monostable TCO-based unit cells are connected horizontally. We fix the distance between leftmost and rightmost polygons by imposing a constant distance between them. Photograph of the corresponding configuration is shown in the right panel. b The normalized elastic energy as a function of φ 1 shows the double-well potential numerically. The inset shows the surface map of the elastic energy as a function of both φ 1 and φ 2, where the highlighted region denotes the valley of the map corresponding to the minimum potential energy trajectory. There exist two minimum states, and the illustrations show the schematic shapes of the pair of TCO cells at these points. Here, the configuration of the folded right cell represents ‘0’, while the one with the folded left cell denotes ‘1’
