Abstract: An energy harvesting system is disclosed that is especially well-suited for use on aerodynamic systems such as guided projectiles or other aerobodies. A series of piezoelectric cantilevers are arranged to capture vibrations from the ambient environment and transduce the mechanical motion from the vibrations into useful electrical energy. The piezoelectric cantilevers can be arranged along different planes from one another to capture different vibrational modes and directions. A power conditioning circuit is included to receive the electrical energy produced by the piezoelectric cantilevers. A storage element coupled to the power conditioning circuit is configured to store charge based on the electrical energy produced by the plurality of piezoelectric cantilever structures. The stored charge can be used to provide low levels of power to certain electrical components on board the aerodynamic system before it has been launched.
