Langasite Bulk Acoustic Wave Resonant Sensor for High Temperature Applications

The high temperature transport properties of langasite, La3Ga5SiO14, were investigated with special attention focused on their potential impact on the utilization of langasite as a mass sensitive resonant platform for high temperature sensor applications. The electrical properties of acceptor and donor doped langasite were examined at temperatures ranging from 700 to 1000C, and pO2 of 1 to 10at...

Film bulk acoustic-wave resonator based ultraviolet sensor

This letter described ultraviolet UV radiation sensing with ZnO based film bulk acoustic-wave resonator FBAR . The resonant frequency upshifted when there was UV illumination on the FBAR. For 365 nm UV light, the frequency upshift was 9.8 kHz with an intensity of 600 W /cm2, and the detection limit of the sensor was 6.5 nW. The frequency increase in the FBAR UV sensor was proposed to be due to ...

Acoustic Voice Measures in Benign Mass Lesions

Objectives: The present study aims to compare acoustic voice parameters in patients with vocal cord nodules, polyps, and normal subjects.  Methods: In this cross-sectional case-control study, the participants were selected by convenience sampling, including 30 patients with vocal polyps group, 38 patients with vocal nodules for the second group, and 42 participants without voice pathologies a...
