Cell operation-version 2

Aself-moving piezoelectric actuator (SMPA) with high carrying/positioning capability is presented in this article. Its Π-shaped mechanical part comprises four piezo-legs, each of which combines the bending vibrations in the first three orders into the motion in the quasi- sawtooth waveform at the driving foot. Besides, a homemade onboard circuit is integrated with the mechanical part to form compact structure.

本文提出了一种具备高承载/定位能力的自驱动压电致动器（SMPA）。其Π形机械部分由四个压电腿组成，每个压电腿将前三个阶次的弯曲振动整合为驱动脚处的近似锯齿波形的运动。此外，一种自制的机载电路与机械部分集成，以形成紧凑的结构。
