Abstract
An electrochemical sensor comprises a first working electrode (10), a second working electrode (16) and a spacer (14) holding the first and second working electrodes (10, 16) in a spaced relationship. At least one of the working electrodes (10, 16) comprises a catalyst or has a layer of catalytic material applied thereto, wherein the spacer (14) is dimensioned such that the spacing of the first and second working electrodes (10, 16) is less than about 40μm. A method of manufacture of such a sensor is also disclosed.
