About

Shuanghui Hao is a leading innovator in the field of precision angular displacement sensing, with a primary focus on magnetic encoder technology. Their research addresses critical challenges in robotics, aerospace, and advanced manufacturing, where compact, robust, and highly accurate position feedback is essential. Hao’s major contributions include the development of a novel absolute magnetic encoder designed for motors with quill shafts or outer rotors—a solution that overcomes the size and contamination limitations of traditional photoelectric encoders. They have also pioneered methods to significantly enhance the accuracy of multipole magnetic encoders using three-phase Hall sensors, and created a multifunctional encoder that outputs both absolute and incremental angles from a single, compact PCB integrating two microcontroller units. Hao’s work on split-type magnetic encoders has further advanced decoding algorithms to eliminate interval misjudgment caused by environmental factors. With their most-cited papers accumulating dozens of citations, Hao’s research is directly shaping the reliability and precision of servo motor control in demanding applications, from robot joint control to machine tool turntables. Their achievements represent a vital step toward more resilient and miniaturized sensing solutions for next-generation automation.
