About

Alessandro Stuart Savoia is a researcher specializing in microfabricated ultrasonic transducer technology, with a particular focus on piezoelectric micromachined ultrasonic transducers (pMUTs) and their applications in precision sensing systems. His work sits at the intersection of microelectromechanical systems (MEMS), acoustics, and applied engineering, contributing meaningful advances to how ultrasound can be harnessed in compact, high-performance devices. Savoia's most cited contribution, "High Resolution, High Frequency Ultrasonic Ranging in Air with pMUTs" (2021, 23 citations), introduced an innovative technique of operating pMUTs below their resonance frequency to achieve wide bandwidth performance — a notable departure from conventional approaches that unlocks superior precision for distance measurement in robotics and industrial machinery. His subsequent 2024 work expanded this vision further, presenting a 1.5 MHz, 12-element 2D pMUT array capable of high temporal and spatial resolution sensing, targeting emerging applications such as gesture control and industrial automation. Through these contributions, Savoia has helped establish pMUT-based air-coupled ultrasound as a viable, high-resolution sensing modality, advancing a technology with broad real-world relevance. His research offers valuable insights for engineers and scientists working at the frontier of ultrasonic sensing and MEMS device design.
