Abstract
Disclosed herein is a planar exhaust gas sensor for sensing the partial pressure of a gas in an exhaust. The sensing element has a modified, non-rectangular overall geometry. A terminal end of the element, onto which external sensor circuits can be attached, has a larger width than a sensor end of the element, in which is located the sensing cell. The reduced size of the sensor end of the element relative allows for more rapid attainment of operating temperature and lower energy consumption.
