About
Guoxi Liu is a pioneering researcher in piezoelectric microactuators and ultrasonic micromotors, with a focus on advanced single-crystal materials. His most cited work introduces a two degrees-of-freedom piezoelectric micromotor fabricated from PIN-PMN-PT single crystals—a material known for exceptional electromechanical coupling. This compact, 2×2×9 mm stator generates standing wave elliptical motions in two orthogonal directions, enabling precise multi-axis control in a miniaturized footprint. The innovation directly addresses the need for high-performance, small-scale actuators in medical devices, robotics, and optical systems. With 40 citations, this 2014 study has become a foundational reference for researchers developing next-generation piezoelectric motors. Liu’s contributions stand out for their elegant integration of materials science and mechanical design, demonstrating how single-crystal piezoelectrics can overcome the limitations of conventional ceramics. His work continues to influence the design of high-torque, low-power micromotors, making him a key figure in the advancement of smart materials and precision motion control.
