Abstract. This paper reports on the use of relaxor ferroelectric single crystal for harvesting aeroacoustic energy from the floor of a structural cavity. In particular, this work examines the optimisation of the single crystal transducer geometry to maximise the energy harvested. The transducers used are 0.175 mm thick  poled Mn-Pb(Mg1/3Nb2/3)O3-Pb(Zr,Ti)O3 (or Mn-PMN-PZT) single crystal fibre composite (or SFC). In this study, the SFCs are bonded to the floor of an experimental cavity within a low-speed wind-tunnel with an airspeed of ~ 60 m/s. Air flowing over the cavity creates an oscillatory pressure cycle that is used as a source of harvestable energy. Detailed multiphysics modelling and parametric optimisation were performed, with model predictions well matched to wind-tunnel experimental results. In particular it is shown that, due to the cavity geometry, an SFC mounted on the cavity floor perpendicular to the wind-tunnel flow produces ~4 times more power than an SFC mounted parallel.
