Influence of feedback on modal shapes and its consequences on broadband energy harvesting
Résumé
We study the effect of feedback on an energy harvester for broadband applications. Using modal analysis we show that it has an influence on modal shape as a side effect of the resonance shifting. We show that the piezoelectric coupling can thus be reduced. Experimental results are in agreement and also reveal that non-linear effects are promoted in some cases.
