(a) Frequency response of black – bare device, red – 1 μm sectional guiding layer and blue – 1 μm Love wave device to varying glycerol-water mixtures exchanged over surface: 5, 10, 30, 50 and 70 % glycerol in distilled water. All data referenced to water. (b) frequency shift as a function of the square root of the density product for the bare device (-○-), 1 μm thick sectional guiding layer (
) and 1μm thick continuous guiding layer (
).
