Abstract
In this paper, a transparent vacuum-encapsulated quartz tuning fork (QTF) is proposed for the first time to improve the quality factor and sensitivity of QTF sensors. Increasing the vacuum considerably improved the quality factor of QTF, and the resonance frequency was also shifted to higher values to 10 Hz. Subsequently, the spectroscopy detection of acetylene gas using an exposed QTF and a transparent vacuum-encapsulated QTF was investigated. The sensitivity of the detection system improved in the presence of the transparent vacuum-sealed QTF. The current findings represent a gateway to subsequent research in photo-thermoelastic spectroscopy.
