Description

This research focus on exploring the effects moisture absorbed by a layer of hygroscopic film coated on the wedge tip along that anti-symmetric flexural (ASF) modes propagate. A laser ultrasound technique is applied to measure dispersion spectra of modes propagating along the wedge tips. Velocity of the ASF mode is found to decrease while the moisture is absorbed by the hygroscopic film. Also, the amount of velocity reduction is found out to be increasing as the frequency increases. Results of the current research suggest the ASF mode can be a new candidate for the application of humidity sensors.
