The flutter of a thin filament can provide a good indication of fluid velocity at small scales. By combining a 'fishtail'-shaped filament's aeroelastic and vortex-forced flutter modes, its oscillation frequency can be confined to scale smoothly with fluid velocity. This principle has been used to produce a low-cost, mm-scale anemometer that measures air flow to ±(5% + 0.5m/s) from 1-25m/s. This paper describes the prototype and the experiments that informed its design, and shows how a similar system could operate at far smaller scales than existing anemometers.
