Abstract
An electrode generally comprises a body, which makes up the electrode and which is formed as a thin flexible polymeric substance such as urethane foam. The electrode body includes a central inner conductive area, which is associated with a first electrode connector. Around the inner conductive area is a non-conductive area formed as a ring around the inner conductive area and there is also an outer conductive area provided as a ring, concentrically arranged around the non-conductive area. Electrode connector (6B) is connected to the outer conductive ring. The electrode body, which has a release tag and is supported on a backing sheet and body can be peeled off the backing sheet using the release tag. The condition of the electrode can be evaluated using a test device, which can for example measure electrical impedance across the electrode via electrodes (6A) and (6B).
