Abstract: Alternating electric fields (e.g., TTFields) may be applied to a subject's body using one or more electrode assemblies that includes a sheet of anisotropic material, at least one layer of conductive material disposed on the front face of the sheet of anisotropic material, and an electrode element positioned behind the sheet of anisotropic material.

This in turn makes it possible to increase the current without exceeding a temperature safety threshold (e.g., 41° C.).

Abstract: Tumor treating fields (TTFields) can be delivered to a subject's body with improved safety and efficacy by determining the condition of participating electrode elements and/or the subject's skin condition under positioned electrode elements. This may be accomplished by applying an AC signal to pairs or groups of electrode elements and taking corresponding impedance measurements. In some embodiments, the impedance measurements are indicative of electrode element condition and/or skin condition. These determined conditions can be used to adjust or pause TTFields treatment, for example to permit skin recovery or to ensure that participating electrode elements will properly function.
