Self-Sustaining Square-Extensional Mode Resonator Oscillator for Mass Sensing in Liquid

Autor: Habiba Begum, Abid Ali, Joshua En-Yuan Lee

Publikováno v: Proceedings, Vol 2, Iss 13, p 976 (2018)

We present a 5.41 MHz square-extensional (SE) mode resonator in closed-loop oscillation for resonant mass sensing in the liquid phase. The resonator has been fabricated in piezoelectric thin film aluminum nitride (AlN) on silicon (Si). The strain pro

AlN-on-Si Square Diaphragm Piezoelectric Micromachined Ultrasonic Transducer with Extended Range of Detection

Autor: Suresh Alasatri, Libor Rufer, Joshua En-Yuan Lee

Publikováno v: Proceedings, Vol 2, Iss 13, p 913 (2018)

We present aluminum nitride (AlN) on silicon (Si) CMOS-compatible piezoelectric micromachined ultrasonic transducers (pMUTs) with an extended detection range of up to 140 cm for touchless sensing applications. The reported performance surpasses the c
