Design and Semi-Physical Experiment of an Impulse Wave Energy Triboelectric Nanogenerator
An impulse air turbine based wave energy triboelectric nanogenerator ( impulse wave energy TENG, IW-TENG) is proposed and designed to be applied in an oscillating water column wave energy conver-sion device, which can efficiently convert low frequency ocean wave energy into electrical energy. The struc-ture and working principle of IW-TENG were elaborated, and two experimental platforms were built to carry out electrode parameter optimization experiments and electrical output performance experiments respectively. The experimental results indicate that using PTFE as the dielectric material of the electrode, the electrical out-put performance is optimal, and the larger the thickness of PTFE, the better the electrical output performance. When the electrode angle of the generator gradually decreases, the short-circuit current tends to rise. IW-TENG was designed and manufactured to conduct a single-wind direction semi-physical simulation experiment to study the electrical output performance under different wind speeds and conduct a capacitor charging experi-ment. The circuit design was driven to light up 33 LEDs. The reliability of IW-TENG and its potential to sup-ply energy to small sensors are verified.
