Planform geometry effects of piezoelectric wind energy harvesting
The focus of Silva-Leon et al was the simultaneous harvesting of wind energy and solar radiant energy, so they did not seek to provide a systematic assessment of composite inverted flags under pure wind excitation. As such, the influence of the geometric parameters of the composite inverted flag on its dynamics and power generation remains unknown.

Harvesting ambient wind energy with an inverted piezoelectric flag
In this work, we report a new and robust approach to harvest ambient wind energy using a piezoelectric flag fixed at the trailing edge and the leading edge free to move called "inverted flag" (Fig. 1 (a)).
