Abstract

One aspect of the invention provides a device that non-invasively determines the concentration of a substance in a target. The device includes a first electrode, a measuring circuit, and a data processor. In one embodiment of the device, the first electrode can be electrically insulated from the target, e.g., a cover layer of insulating material covers the first electrode.
