The paper presents the design, configuration and experimental evaluation of a piezoelectric energy harvesting system intended for footstep-based power generation. Multiple piezoelectric sensor array configurations were investigated alongside the integration of a voltage-doubler circuit to enhance harvested electrical output. Configurations ranging from a single sensor to large-scale series-parallel arrays comprising 32 sensors were tested under varying mechanical loading cycles. The experimental results demonstrate that increasing the number of sensors significantly improves voltage and power output, while the voltage-doubler circuit stabilizes and amplifies the harvested energy, particularly when arranged in hybrid series-parallel configurations. The optimal configuration—eight sensors in series and four in parallel— produced a maximum power output of approximately 0.277 mW at 120 loading cycles. These results validate the feasibility of piezoelectric footmats for powering low-power electronic devices.
The increasing global demand for sustainable and decentralized energy solutions has intensified research into alternative energy harvesting technologies.
