“…The voltage increases with respect to the frequency which can be attributed to the heightened excitation frequency, resulting in an accelerated relative motion between the magnet array and the coil array. Hence, higher voltages are induced within the coil (according to (27)). The frequency (described in average value) of the output voltage also can verify it.…”

“…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.

Triboelectric nanogenerator (TENG) has emerged as a novel nanotechnology for energy harvesting and self‐powered sensing via utilizing various low‐frequency mechanical energies throughout the surrounding environment. However, designing TENG with high physical robustness, flexibility, and output performance is rather challenging. This study develops monolithic conjugated microporous polymer aerogel (CMPA) with delocalized π‐conjugation to construct TENG with a robust porous structure. The as‐produced CMPA is composed of hollow intertwined nanotubes with a high degree of flexibility and high specific surface area (up to 528 m2 g−1). Due to its intrinsic nature of conjugated electron transfer and architectural characteristics, the CMPA‐based TENG (effective area: 4.9 cm2) shows a high sensitivity to mechanical force and excellent electric output (open‐circuit voltage: 72 V, short‐circuit peak current: 3.2 µA and transferred charge: 48 nC). Moreover, the CMPA‐based TENG can charge micro‐electronic devices and sense human motions. This work will inspire the design of aerogel‐based electronic devices and the management of renewable energy resources.
