The electrical voltage, current and power output is calculated due to harmonic forced vibration of shell energy harvester. So five electromechanical equation together with Gauss equation is solved for doubly curve shell harvester in steady state condition in order to derive voltage, current and electric power output. The effect of shell curvature in cylindrical and spherical shells, the harvester series or parallel connection of layers and thickness of substrate and piezoelectric layer, is also considered in order to obtain maximum power output. The results show for small shell curvatures a high frequency load is needed to obtain maximum power and when the shell arc length is three times to...
