When the length of the piezoelectric elements is low compared to the typical wavelengths of bending deformations, governing equations are derived in the form of continuous coupled fluid-solid-electrical equations. These equations are used to perform a linear stability analysis of the coupled system, and a parametric study of the efficiency of the energy transfer from the fluid-solid system to the electrical system addressing both linear and nonlinear dynamics. %G English %L hal-01141116 %U https://hal-ensta-paris.archives-ouvertes.fr/hal-01141116 %~ X %~ ENSTA %~ CNRS %~ X-LADHYX %~ X-DEP %~ X-DEP-MECA %~ ENSTA_UME
