摘要

Love wave sensor has the highest sensitivity among surface acoustic wave sensors. The development of Love wave biosensors and chemical sensors are reviewed in this paper. The effects of the guided layer materials and their thickness as well as the piezoelectric substrates and their cuttings on the sensor sensitivity and temperature stability are discussed. We point out that the high frequency resonator type sensor with a polymer guide layer can further increase the sensitivity of Love wave sensors.
