Re-writeable memory: path dependency with indepedent bistable rotating beams

The switching sequence of bistable elements are traditionally tuned by interactions. However, designing these interactions for target sequences is highly non trivial and remains an unsolved mystery. Here, we propose a novel strategy to design path dependent switching sequences of bistable elements using a single input function. By placing bistable beams on a rotating frame, by controlling the angular position we introduce two orthogonal forces coupled through their time-derivates(centrifugal, and Euler forces). This strategy opens new avenues toward simplified designed systems finding applications in soft robots, rewritable memory in materia, and microfluidics.
