Stress-induced frequency shifts of the thickness-shear vibration of rotated Y-cut langasite resonators are studied with the electrode considered. The relationship between mass loading and force-frequency coefficients is explored for several kinds of electrode materials. Comparisons between Y-cut langasite and AT-cut quartz resonators are also presented.
