“…Xie et al established a mathematical model of output charge and voltage of piezoelectric plates by the Airy linear wave theory in combination with the elastic beam model, which can be applied in ocean wave energy recovery and achieve up to 30 W recovered power [25]. Wahad et al also modeled and simulated it, and obtained the relationship between its open-circuit output voltage, maximum deflection, as well as internal stress and device size, and applied pressure amplitude [26]. On the other hand, Moeenfard et al used the random vibration theory to model a stationary disk piezoelectric energy harvester around the plate and obtained the statistical parameters of the dynamic characteristics of the plate and the captured energy voltage [27].…”

To address the problem that piezoelectric energy harvesters are difficult to apply in certain environments, this paper establishes the theoretical study of the intermediate fixed disc piezoelectric energy harvester (IFDPEH) based on the unimorph under concentrated force. The reliability of the model was indirectly verified by numerical simulation and Computer-Aided Engineering (CAE) simulation. The effects of load, radius ratio (piezoelectric layer/intermediate support), thickness ratio (piezoelectric layer/total thickness), and elastic modulus ratio (substrate/piezoelectric layer) on electrical energy were studied. The results indicate that the radius/thickness ratios of the IFDPEH based on aluminum and beryllium bronze are 0.05/0.31 and 0.05/0.48, respectively. In addition, through parameter comparison, it is found that the most important parameters affecting IFDPEH power are radius ratio and large load. The results are demonstrated to be meaningful for broadening the application of piezoelectric energy harvesters by the derived closed-form equations for the electrical energy along the diameters of the piezoelectric discs in the z-direction.
