Abstract
A method and device for converting fluidic kinetic energy into oscillatory mechanical motion is disclosed. A mechanical structure of finite stiffness is coupled to a fluid-dynamical control surface the thrust from which is oscillated in direction. The coupling thereby induces oscillations in the structure, the magnitude of which can be controlled by the degree of mechanical resonance between the oscillation rate of the fluidic thrusting and the structure'"'"'s resonance frequency. The resulting mechanical energy can be converted into electrical energy using either piezo-electric or electromagnetic means.
