Abstract
The increasing demand for sustainable energy solutions has necessitated the exploration of novel harvesting methods, particularly within high-impact environments. This study presents the design and development of a kinetic energy harvesting system integrated into a speed boxing bag, capable of converting mechanical punch impacts into electrical energy. The system utilizes embedded piezoelectric transducers to capture kinetic energy, which is subsequently processed by an ESP32 microcontroller and stored in a capacitor bank. To ensure accurate energy quantification, a threshold-based peak detection algorithm was developed to filter ambient noise and identify valid strike events. The system features an Internet of Things (IoT) architecture, facilitating real-time data regulation and cloud-based monitoring via a custom mobile application. Experimental validation and user evaluations conducted under ISO/IEC 25010 quality standards demonstrated that the system generates sufficient energy to power low-voltage electronics, such as sensors and LED indicators. The system received high user ratings for functional suitability (M=4.59) and usability (M=4.61). These findings confirm the feasibility of transforming boxing equipment into decentralized energy-harvesting platforms, thereby supporting the integration of self-powered smart technologies into fitness infrastructures.
