In this paper, an exact analytical solution is obtained for free flexural vibration of a cantilever piezoelectric panel carrying a rigid mass. The cantilever piezoelectric panel, commonly used in vibrational energy harvesting, may consist of a single layer of piezoelectric material (unimorph), two layers of piezoelectric material with or without a center core (bimorph), or multiple layers of piezoelectric material (multimorph). For an immediate application to a class of piezoelectric energy harvesting devices, the analytical procedure is presented for vibration modes, which are symmetric with respect to the panel major centerline. Numerical results and comparisons of several example applications show that the proposed scheme is accurate and convergent.
