Background : With the advancement of digital technology, the increasing use of smartphones, wearable devices, and Internet of things(IoT) technologies has raised concerns about digital carbon footprints. The greenhouse gas emissions generated during the production, use, and disposal of electronic devices are becoming a significant environmental issue, necessitating sustainable solutions. Body energy harvesting (BEH) technology offers the potential to convert human kinetic energy into electrical energy, thereby reducing dependence on conventional energy sources. However, its adoption remains limited due to a lack of user awareness and practical usability challenges in everyday life. This study explores the potential applications of body energy harvesting and proposes a service design strategy to promote sustainable energy practices and to reduce digital carbon footprints. Methods : This study employed a mixed-methods approach to comprehensively evaluate the user experience of body energy harvesting services. First, a survey was conducted to analyze outdoor activity behaviors and digital device usage patterns. Subsequently, experimental observations were carried out to capture participants’ real-time reactions and usage patterns, utilizing the think-aloud method for an in-depth analysis of user experiences. Finally, in-depth interviews were conducted to derive qualitative insights. The study applied the perceived value (PERVAL) scale and the theory of planned behavior (TPB) to ensure the reliability and validity of the data. Results : The findings of this study indicate that body energy harvesting services positively impact reducing digital carbon footprints and fostering sustainable energy consumption habits. Participants reported high motivation in collecting and utilizing energy through physical activities, with the crew-based social engagement feature proving effective in encouraging long-term participation. However, improvements in device weight reduction and more intuitive data visualization were identified as necessary enhancements. Conclusions : This study confirms the potential of body energy harvesting services in reducing digital carbon footprints and promoting sustainable energy consumption. The study provides foundational insights into how body energy harvesting technology can establish itself as an eco-friendly and practical solution in everyday life. Furthermore, the study offers strategic design directions for building a sustainable digital environment.
