Abstract:
A method for measuring the temperature and other properties of a chemical/biological measurand at generally the same location on a sensing surface of a sensor comprising the steps of:subjecting the sensing surface of the surface acoustic wave sensor directly to the chemical/biological measurand;producing a series of surface acoustic waves on the said surface of said sensor;producing a series of surface skimming bulk waves;propagating said surface skimming bulk waves at generally an angle to said surface acoustic waves so that accurate measurements of the temperature and other properties of the chemical/ biological measurand can be made at generally the same location on the sensing device;detecting said surface waves after transmission thereof across said surface; andmeasuring parameters of said detected surface waves to determine the temperature and other properties of the chemical/biological measurand at generally the same location on said surface.
