The team of Professor Liu Yingxiang at the State Key Laboratory of Robotics and Systems, Harbin Institute of Technology, published a paper titled "A Review of High-Performance Piezoelectric Actuators for Extreme Manufacturing" in the journal Extreme Manufacturing, proposing a strategy for evaluating piezoelectric actuator performance along five dimensions: scale, speed, force, degrees of freedom, and precision. The article explains the regulation mechanisms of performance in each dimension, analyzes the performance bottlenecks under different operating modes, and proposes a new approach of multi-mode fusion piezoelectric actuation to simultaneously achieve high precision, large stroke, large output force, and high speed. Harbin Institute of Technology is the sole completing institution and corresponding institution of the paper; Professors Liu Yingxiang and Deng Jie are co-corresponding authors, and doctoral student Sun Jianhua and associate researcher Guan Jinghan are co-first authors.
