AB  - Autonomy and minimal disruption are key desirable features  for  sensors  to  be  deployed  in  medical,  industrial, vehicle and infrastructure monitoring systems. Using a passive structure to transduce the quantity of interest into an acoustic or electromagnetic  wave  could  offer  an  attractive  solution  for remote  sensing,  lifting  the  requirements  of  installing  active materials,  electronics,  and  power  sources  in  remote, inaccessible, sensitive, or harsh environment locations. Here, we report a simple cavity and ball structure that transduces fluid flow through a pipe into an acoustic signal. A microphone on the outside wall of the pipe records the intensity and arrival rate of the sound pulses generated by collisions between the ball and the cavity walls. Using this approach external measurement of flow is demonstrated with adequate repeatability before any acoustic signal processing. This result is expected to open the way  to  the  implementation  of  passive,  remotely  readable sensors for fluid flow and other fluid properties of interest.
