Abstract
The present invention provides an electrode assembly for use in a transdermal analyte sensor operating in an alternating polarity mode in which a single electrode element provides both the counter electrode and iontophoretic electrode functions. By combining both the functions of the iontophoretic and counter electrode, the surface area of the electrode with respect to each function may be made larger. In turn this increases the ability of the electrode to deliver the required electrical field over a larger area when operating in the iontophoretic mode as well as increasing the ability of the counter electrode to compensate for the larger sensing electrode facilitated by this new design.
