Abstract
An electrical energy harvesting device for harvesting electrical energy from a pulsed impact loading event. The device including: a piezoelectric element configured to be loaded and unloaded to a first load level by the pulsed impact loading event; and a first inductor coupled to the piezoelectric element configured to be loaded and unloaded to a second load level by the pulsed impact loading event, wherein the piezoelectric element and the first inductor together operate as a first inductor/capacitor (LC) resonant circuit having a first resonance frequency and wherein the loading of the first inductor lags in time the loading of the piezoelectric element.
