Abstract
A multilayered ceramic integrated sensor 200 for monitoring auto exhaust gases is capable of existing in the relatively harsh environments of the exhaust stream of an internal combustion engine. The integrated sensor 200 may include discrete devices such as an oxygen sensor 104, a hydrogen sensor 206, an NO.sub.x sensor 208, and a carbon monoxide sensor 210. The device 200 may further include a temperature sensor 202 as well as total combustion calorimetric sensor 102. The multilayered ceramic integrated sensor may be fabricated from a plurality of layers of ceramic material disposed in stacked relationship with respect to one another.
