About

Marco Ferrera is a leading researcher in the field of microelectromechanical systems (MEMS), with a focused expertise on piezoelectric micromachined ultrasonic transducers (pMUTs) for advanced sensing applications. His primary research areas include high-resolution ultrasonic ranging, air-coupled ultrasound, and the development of novel transducer arrays for robotics and industrial automation. Ferrera’s major contributions center on pushing the performance limits of pMUTs; his seminal 2021 work introduced a groundbreaking technique for operating pMUTs below their resonance frequency to achieve a wide bandwidth, enabling high-resolution, high-frequency distance measurements in air. This work has garnered 23 citations, establishing a foundation for subsequent innovations. Building on this, his 2024 paper presents a state-of-the-art 1.5 MHz, 12-element 2-D pMUT array designed for superior temporal resolution, a critical advancement for precise gesture control and industrial sensing. With a growing citation impact, Ferrera’s work is instrumental in transitioning pMUT technology from theoretical research to practical, high-performance systems, marking him as a key innovator in the next generation of ultrasonic sensing.
