📄 原文摘要

electrostatic and piezoelectric actuators are crucial in small-scale electromechanical applications, but they significantly impact the overall system weight, especially in microrobotics [1,2,3]. These systems operate at low frequencies (10’s Hz [2]) and require a significant voltage conversion ratio to generate high voltages (in the tens of volts [4]) from low-voltage sources like electrochemical batteries (3-to-5V), all while meeting stringent size and weight constraints (1’s g [2]), and flight endurance (10’s of min [3]). Due to their primarily capacitive nature, these actuators demand mostly reactive power (CxV(F) in the 10’s mW range [2] to efficiently drive dielectric materials (Cx=1’s to 100’s nF [5]). Effective management of this reactive energy is essential
