文摘

An inductor-free power-management principle based on automatic switches between serial-connected and parallel-connected capacitor is proposed for TENG. A motion-triggered power-management unit built-in TENG is fabricated, with 5 times charging rate demonstrated. We also identifies advantages of this power-management unit including capability for harvesting low power/frequency scale energy, high scalability, and light weight. This design will pave a new approach for achieving high-efficient portable TENG-based self-powered system.
