Finding an effective, clean and sustainable power source, which is independent on traditional power sources, is becoming more necessary. The current work is under an ongoing project for Energy harvesting from human body motion, which aims to create an applicable physical system that uses a pendulum-to-rotary power conversion system to transform the kinetic energy of human body motion into electrical energy. The need for efficient, light and wearable power source mechanism is needed in different applications, such as mobile device chargers, smartwatches, fitness trackers and portable personal fans. In the current work a wearable device system is designed to improve energy production and make the device comfortable and user-friendly. Motion and power calculations are presented and the developed design is discussed in different studied cases. The generated power shows the effectiveness of this application. The studied device can be widely used in applications where energy is harvested and stored utilizing contemporary energy storage devices, allowing low-power gadgets to run continuously without needing to be charged. The initiative sets itself apart by offering an application-focused strategy that illustrates a practical way to incorporate energy harvesting into daily tasks.
