A non-sterile arrangement of multiple electrical conductors intended to be used in conjunction with an electrical impedance spectrometer (EIS) to apply a small electric current to the skin during EIS analysis of neoplastic skin. It is typically a small cover that fits over a probe and may be textured (e.g., with pins) to penetrate the outermost layer of skin. This is a single-patient device intended to be used for the duration of the treatment (single-use) before being discarded.
