## Summary

Professor Liu Yingxiang's team at the State Key Laboratory of Robotics and Systems at Harbin Institute of Technology (HIT) published a review on high-performance piezoelectric actuators in Extreme Manufacturing, proposing a five-dimension performance evaluation strategy covering scale, speed, force, degrees of freedom, and precision. The article explains the performance regulation mechanisms of each dimension, analyzes the performance bottlenecks of different working modes, and proposes a new approach of multi-mode fusion piezoelectric actuation to achieve high precision, large stroke, large output force, and high speed simultaneously.
