Paper Abstract

A detailed analysis of the quality factor, the resonance frequency and the electrical resistance of custom quartz tuning forks (QTFs) having different geometrical parameters is reported. We implemented custom QTFs in a quartz enhanced photoacoustic sensor targeting water vapor detection and compared the fundamental and first overtone flexural modes gas sensor performances.
