Annotation: This dissertation investigates piezoelectric cantilever energy harvesters for autonomous systems. The aim is to optimize the beam shape to maximize strain in the active layer while maintaining eigenfrequencies and manufacturability. A gradient projection method with finite element modeling is applied to optimize thickness distribution. Results demonstrate a significant increase in generated electrical output and improved strain localization compared to uniform beams, with mode-specific geometries identified for the first and second eigenfrequencies. Experimental validation confirms the accuracy of the proposed method and the effectiveness of the optimized designs.
