About

Dr. Duan Jian Goh is a leading innovator in microelectromechanical systems (MEMS), specializing in piezoelectric micromachined ultrasonic transducers (pMUTs) for high-precision sensing. His research focuses on advancing ultrasonic ranging and vibration detection technologies, with critical applications in robotics, industrial automation, and proximity sensing. Dr. Goh’s major contribution lies in pioneering the operation of pMUTs below their resonance frequency—a technique that dramatically widens the device bandwidth while maintaining high resolution. His seminal 2021 work, "High Resolution, High Frequency Ultrasonic Ranging in Air with pMUTs," which has garnered 23 citations, demonstrated how this approach enables precise distance measurements in air. Building on this foundation, his 2024 paper on "Close Range and High-Resolution Detection of Vibration by Ultrasonic Wave Using Silicon-on-Nothing PMUTs" introduces novel cross-correlation methods for accurate time-of-flight detection, achieving exceptional resolution at close range. With a growing citation impact, Dr. Goh’s work is shaping the next generation of compact, high-performance ultrasonic sensors, bridging the gap between fundamental MEMS physics and practical, real-world sensing solutions.
