Cylindrical Shell and Metal Wire-Based Omnidirectional Wind-Driven Triboelectric Nanogenerator
Image Image Image Image Image Image Image
Fig. 1 (a), (b) Schematic diagram of the omnidirectional wind-driven triboelectric nanogenerator. The proposed WTENG is composed of flexible polymer film and a rigid column
Fig. 2 (a) Alignment principle of the cylindrical shell. (b) Working principle of the WTENG. When the wind blows around the column, a vortex is created that causes the shell to vibrate
Fig. 3 Experiment setups for measuring voltage and current
Fig. 4 (a) Open-circuit voltage of the harvester when the wind speed changes. (b) Enlarged graph of the data at 3 m/s wind speed
Fig. 5 Influence of wind speed on RMS voltage of the WTENG with three different film diameters
Fig. 6 RMS voltage of the WTENG for different wind directions
Fig. 7 (a) Output voltage and power of the fabricated WTENG with various resistive loads. (b) The change in voltage across the capacitors with time when the output is passed through a full-bridge rectifier circuit and stored in two capacitors
