About

Dr. Sagnik Ghosh is a leading researcher in microelectromechanical systems (MEMS) and ultrasonic sensing, with a focus on advancing piezoelectric micromachined ultrasonic transducers (pMUTs). His most-cited work, "High Resolution, High Frequency Ultrasonic Ranging in Air with pMUTs" (2021, 23 citations), introduces a groundbreaking technique for operating pMUTs below their resonance frequency to achieve wide bandwidth. This innovation enables high-resolution, high-frequency ultrasonic ranging critical for applications in robotic navigation, industrial automation, and precision distance measurement. By overcoming traditional bandwidth limitations, Dr. Ghosh’s contributions enhance the accuracy and reliability of pMUT-based systems, positioning them as key components in next-generation sensing technologies. His work bridges fundamental MEMS design with practical engineering challenges, earning recognition for its impact on both academic research and industrial applications. With a growing citation record, Dr. Ghosh continues to shape the field of ultrasonic sensing, offering scalable solutions for real-world distance measurement and object detection.
