Abstract :
Experimental studies of ZX-LiNbO3 acoustic plate modes as detectors for dilute electrolyte or metal ion solutions are reported which indicate a strong acousto-ionic interaction. The results show an increase in sensitivity and resolution by more than two orders of magnitude compared with previously reported acoustic wave sensors.
