Abstract
This study aims to analyze the effect of load variation on the output performance of piezoelectric sensors, compare the performance of series and parallel circuit configurations, and evaluate the effectiveness of Zn-doped CDs derived from OPEFB as a coating material to enhance the mechanical performance of piezoelectric sensors for electrical energy generation. The design of a piezoelectric sensor prototype integrated into a speedbump system. Zn-doped CDs were synthesized using the sol-gel method and applied as a coating layer on the piezoelectric sensor using epoxy resin. The synthesized materials were characterized using XRD, SEM, and UV-Vis spectroscopy. Sensor performance testing was carried out using load variations on a single sensor sample as well as on series and parallel circuit configurations. The measured parameters included output voltage, current, and power under both AC and DC conditions. The performance evaluation demonstrated that the PLRCZ sample, consisting of a piezoelectric sensor coated with resin and Zn-doped CDs, produced the highest electrical output among all coating variations of 8,21×10⁻⁴ W. In addition, the parallel configuration generated the highest output of 1×10⁻² W. The output voltage, current, and power increased with increasing applied load, indicating that the Zn-doped CDs coating improved pressure distribution and mechanical stability on the sensor surface.
