Magnetic Force Enhanced Sustainability and Power of Cam-Based Triboelectric Nanogenerator
Effect of magnetic spring in MC-TENG. (a) Controlled magnetic repulsive force by different magnets (,, and ) at the bottom substrate. (b) Decreased contact force by increasing repulsive forces with different magnets. (c) Corresponding output voltages. (d) Output currents. (e) Contact-separation times in MC-TENG with a magnetic spring.
