Using a combination of experiments, theory, and simulations, researchers demonstrate how to encode information bits on a long cylindrical elastic shell in the form of a sequence of stable dimples, similar to Braille, and which can be written anywhere along the cylinder using a mechanical stylus and erased; such a system could serve as the basis for small-scale mechanical memories, according to the authors.
