Abstract
Abstract A method of making a patterned laminate includes ablating through a portion of a metallic layer with a laser, to form a pattern in the metallic layer, where the metallic layer is on and in contact with an insulating substrate. The patterned laminate may be patterned to form electrodes, and can be formed into an electrochemical sensor strip.
