Vortices shed by leading-edge tubercles in a finite wing provide the means for passive stall control at low Reynolds number. Piezoelectric film sensors are used as flexible fringe elements at the trailing edge of the wing so that small amounts of energy may be harvested from fluid-structure interaction. A wind tunnel testing campaign is conducted comprising extensive parametric power measurements.
