About

Yi-Da Lee is a researcher specializing in piezoelectric actuation and precision motor design, with a particular focus on multi-degree-of-freedom (multi-DOF) systems. His most-cited work introduces a novel stator design for a two-degree-of-freedom traveling-wave rotary piezoelectric motor, where two sets of piezoelectric actuators are arranged perpendicularly around a spherical surface. By applying phase-shifted voltages to neighboring actuators, Lee achieves controlled rotary motion in multiple axes, advancing the capabilities of compact, high-precision motors. This contribution is especially relevant to applications in robotics, optical alignment, and micro-positioning systems, where traditional electromagnetic motors fall short. Though his citation count is modest, Lee’s work demonstrates foundational engineering insight into the integration of piezoelectric arrays for complex motion control. His research highlights the potential of smart materials in miniaturized actuation, offering a pathway toward more versatile and efficient motor designs. For students and researchers exploring piezoelectric systems, Lee’s work serves as a clear example of how structural innovation and phase-driving techniques can expand the functional range of conventional motors.
