The 10-cm sheet of smart transparency is driven by “ripple power“; waves of electrical current flex a thin, 10cm sheet, driving thin pockets of air from front to rear underneath. The prototype, described in Applied Physics Letters, moves at speeds of around a centimetre per second. Improvements to the design could raise that to as m
