Footstep Power Generation Using Piezoelectric Sensor and Arduino UNO
Abstract: This paper investigates a renewable approach to energy production by capturing kinetic energy from footsteps using piezoelectric sensors integrated with an Arduino Uno. The core innovation lies in configuring multiple circular piezoelectric discs within the footpad to enhance energy output. The study primarily aims to evaluate and compare various sensor connection arrangements to identify the setup that generates the highest voltage and power from human movement. Four distinct configurations- series, parallel, series-parallel, and parallel-series- were designed and practically tested using 35 mm diameter, 3.36 mm thick piezoelectric discs. A total of eight piezo sensors were strategically placed in high-pressure zones of the sole pad to maximise energy conversion. Tests revealed that a single footstep exerting roughly 686.7 N of force could produce a voltage of up to 4 V when using either parallel or parallel-series configurations. Conversely, series arrangements consistently yielded the lowest voltage levels. Among all, the parallel configuration proved most effective for charging applications, delivering a stable and higher DC output over approximately 1000 steps.
