In-liquid bulk acoustic wave resonators for biosensing applications
Gravimetric sensors based on thin-film bulk acoustic wave (BAW) resonators operating between 1-5 GHz have tremendous potential as biosensors because they are inexpensive, label-free, fast and highly sensitive. The two main challenges in this objective are: the conventional longitudinal mode …

Architecture for ultra-low power multi-channel transmitters for Body Area Networks using RF resonators
… of transmitters in these BANs is developed. RF Resonators, and in particular Film Bulk Acoustic Wave Resonators (FBARs) are explored as carrier frequency generators since they provide stable frequencies without the need for PLLs. The frequency of oscillation is directly modulated to generate …

ALUMINUM SCANDIUM NITRIDE (AlScN) FILMS FOR MICROELECTROMECHANICAL SYSTEMS (MEMS)
… the origins of AOGs and stress in these films. Bulk acoustic wave resonators fabricated from 400 nm and 600 nm thick low stress and AOG free Al0.68Sc0.32N films grown directly on Si demonstrate high frequency operation of 3.6 and 4.8 GHz, high electromechanical coupling > 23%, and quality …
