An oxygen sensing element adapted primarily to determine an oxygen partial pressure of a measurement gas, including a solid electrolyte body having a surface, at least a portion of which is undulated. An electrode is formed on the undulated portion of the surface of the solid electrolyte body. The electrode is covered by a porous protective coating, such that the electrode is exposed to the measurement gas through the porous protective coating. The undulated portion of the solid electrolyte body has an average height of at least 50 microns between the top and bottom of its convexed and concaved parts. At least a portion of the porous protective coating is positioned within at least one of the concaved parts of the undulated portion of the solid electrolyte body. A method of producing the instant sensing element is also disclosed. |
