Self-powered and speed-adjustable sensor for abyssal ocean current measurements based on triboelectric nanogenerators
An ultra-compact deep-sea current sensor utilizing triboelectric nanogenerator technology is developed.Measurements conducted at a depth of 4,531 meters demonstrated that the instrument can accurately measure a wide range of flow velocities,from 0.02 m/s to 6.69 m/s,with the highest sensitivity.
