Inthis paper, we study the electrical impedance response of different sizes of commercial piezoelectricdiscs for a wide range of frequencies (without and with mechanical load for0.1–1000 kHzwithresolution 20 Hz).The piezoelectric effect, along with its associated materials, fascinated researchers in allareas of basic sciences and engineering due its interesting properties and promising potentials.Sensing, actuation, and energy harvesting are major implementations of piezoelectric structures instructural health monitoring, wearable devices, and self-powered systems, to name only a few. Theelectrical or mechanical impedance of its structure plays an important role in deriving its equivalentmodel, which in turn helps to predict its behavior for any system-level application, such as withrespect to the rectifiers containing diodes and switches, which represent a nonlinear electrical load. Inthis paper, we study the electrical impedance response of different sizes of commercial piezoelectricdiscs for a wide range of frequencies (without and with mechanical load for0.1–1000 kHzwithresolution 20 Hz). It shows significant changes in the position of resonant frequency and amplitudeof resonant peaks for different diameters of discs and under varying mechanical load conditions,implying variations in the mechanical boundary conditions on the structure. The highlight of ourwork is the proposed electrical equivalent circuit model for varying mechanically loaded conditionswith the help of impedance technique. Our approach is simple and reliable, such that it is suitable forany structure whose accurate material properties and dimensions are unknown
