Energize Your Walk: Developing a Self - Charging Power Bank with Real - Time Activity Monitoring

The increasing reliance on portable electronics has heightened the demand for effective and environmentally friendly charging solutions. Traditional power banks, which require external power sources, can be inconvenient for consumers on the go. This study proposes a self-charging power bank that harnesses biochemical energy produced during physical activities such as jogging or walking. By integrating energy harvesting technology with health monitoring features, this innovative device aims to recharge itself autonomously while tracking metrics like steps taken, calories burned, and power generated. Supported by existing research demonstrating the potential of wearable technology to convert kinetic energy to electrical energy (Zhang et al., 2020; Khalifa et al., 2020), this study aligns with global trends toward sustainable energy solutions and the integration of health features in consumer electronics. The project objectives include designing an efficient energy harvesting mechanism, developing a user-friendly activity tracking application, enhancing user engagement through feedback, and promoting sustainability by reducing reliance on non-renewable energy sources. This research not only addresses practical user needs but also contributes to public health initiatives by encouraging physical activity and reducing battery waste, thus paving the way for future advancements in personal electronics.
