ABSTRACT:
Breakdown-mediated charge transfer is made to occur at the surface of a dielectric and its rate is limited by a defined dielectric polarization level and frequency for safe use in a clinical setting. Measurement is accomplished directly by an optical method and indirectly by a high frequency current detection method. The optical method is made reliable through a sealed construction technique. The quality of diagnostic readings supplied by both methods are made more reliable by a repeatable means of force application.
