Abstract
Abstract—Surface acoustic wave-based high-sensitivity selective temperature sensor prototypes have been developed that operate independently of the rest of the physical parameters of liquids. The selectivity is provided by excluding physical contact between a surface acoustic wave and a tested sample. To enhance the sensitivity, the wave path from a transmitter to a receiver has been increased and the fifth wave harmonic has been used. The operation threshold of the prototypes has been reduced to 0.03–0.005°С.
