Abstract
A sensor is disclosed for analyzing information, such as interfacial interactions, found in various systems. A sensor is located proximate to an interface that is to be studied. The sensor is actuated in order to produce acoustical signals. The frequency of oscillation of the sensor is varied in order to enable the sensor to produce acoustical signals at different harmonics. The different acoustical signals are used to analyze the system at various distances from the surface of the sensor.
