Efficient harvesting of random mechanical energy
Utilizes a coaxial counter-rotating unit to convert random, low-frequency, small-amplitude mechanical motions into high-speed relative rotation, significantly improving energy conversion efficiency; a soft-contact fur layer replenishes triboelectric charges, enhancing output and durability.
