Abstract

A method for detecting extent of cross-linking of a high impedance material during a shelf life, slow state transition or during use, the method including: applying a test signal through a sensor to the material and through a reference material; determining a voltage difference between the test signal applied to the material and the reference material as the reference voltage; and correlating the voltage difference as a relative indicator of the extent of chemical change which has occurred within the material. Also disclosed is a device for implementing the subject method.
