Abstract
Alternating electric fields (e.g., tumor treating fields or TTFields) can be applied to a subject's body using electrode assemblies that are made from two discrete subassemblies, which are removably and adhesively connectable to each other. As long as the two subassemblies remain in intimate contact (which can be determined, e.g., by measuring an electrical resistance or an optical reflectance), the system applies an AC voltage to the electrode assemblies. But if (a) the subassemblies within any given electrode assembly become separated (or even begin to separate), or (b) the subassemblies within any given electrode assembly are not aligned correctly, then the system will turn off the AC voltage to that electrode assembly.
