About
Dr. Yul Koh is a leading innovator in the field of microelectromechanical systems (MEMS), with a primary focus on piezoelectric micromachined ultrasonic transducers (PMUTs) and their application in high-precision sensing. His most notable contribution is the development of a groundbreaking method for close-range, high-resolution ultrasonic vibration detection using silicon-on-nothing PMUTs. In his highly cited 2024 work, Dr. Koh demonstrated that by operating PMUTs below their resonance frequency and employing advanced cross-correlation techniques, it is possible to achieve exceptional time-of-flight (ToF) ranging accuracy in air. This work, which has already garnered significant attention, overcomes fundamental limitations in conventional ultrasonic sensing, enabling precise detection of minute vibrations at very short distances. His research is pivotal for advancing non-destructive evaluation, proximity sensing, and human-machine interfaces. With a growing citation impact, Dr. Koh’s innovative approach is establishing new benchmarks for sensitivity and resolution in MEMS-based ultrasonic systems, positioning him as a rising authority in next-generation acoustic sensing technology.
