Abstract
The method of making a wide range oxygen sensor of the present invention enables ease of handling and processing, particularly in a mass production environment. This process comprises forming planar composite elements of the sensor where the elements are individually laminated. These laminated composites are easily handled and readily stacked. Furthermore, electrodes and electrode leads can be readily deposited on the laminated composites, across the intersection of the various materials forming the composite. After deposition of the electrodes, leads, and a heater, the elements are stacked accordingly and laminated to produce the oxygen sensor.
