“…With the advance in these electronic devices, inadequacies of the conventional battery have been more apparent. Conventional batteries not only contaminate the environment but also need periodic charging or replacement [23][24][25][26][27][28], piezoelectric [29][30][31], electromagnetic [32][33][34], etc. For example, Yang et al [35] fabricated a backpack (weighed 2.0 kg) based on the triboelectric nanogenerator which can capture energy from human walking.…”

The fast advances in wearable electronic devices require clean and wearable power sources. This study presents a wearable electromagnetic energy harvester (EMEH) with high output performance mounted on the knee to obtain human vibration energy. The design forms a circumferential step-change magnetic field with high electromechanical coupling for high-efficiency energy conversion. We first formulate a theoretical model and simulate the analytical voltage via MATLAB. To predict the output performance of the EHEM, we conduct simulations via ANSYS. Subsequently, Experiments are conducted to explore the output performance of the harvester in terms of the voltage, the output power, and the charging rate. The prototype generates a peak power of 3.88 W with a 449 Ω resistor under the excitation of 2 Hz. Additionally, the prototype charges a battery to 33.9% within 300 s at a running speed of 8 km/h. This study provides a new perspective for advancing the development of watt-level self-powered wearables.
