Abstract

fetched live from OpenAlex

Abstract Due to the low output power of triboelectric nanogenerators (TENGs) in harvesting wind energy, this work proposes a hybridization scheme with electromagnetic generators (EMGs) to improve the power density of TENGs. Then, a novel configuration is designed and experiments of impedance matching and output power are conducted to compare the power density of triboelectric nanogenerators with/without electromagnetic generators under a wind speed of 5.5 m s −1 . According to the experimental results, the power density of the hybrid generator is 29.8 times higher than that of the triboelectric nanogenerator without electromagnetic generators (TENG‐WEMGs). To further demonstrate the output performance of the hybrid generator, experiments of charging capacitors and powering electronics are implemented at the same wind speed. Based on the experimental results, a capacitor of 2.2 mF is charged to 25.7 V within 20 s, 170 LEDs are lit, and the Bluetooth tracker is driven to transmit signals in real time. In addition, this work investigates the influences of different resistant loads of EMG on the average power of TENGs. This work can be of great significance to further develop self‐powered sensors.

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
