Abstract

A sensor element for gas sensors for determining the concentration of particulates in gas mixtures, in particular soot sensors having at least one first measuring electrode applied to an electrically insulating substrate and at least one second measuring electrode, a voltage being applicable to the first and second measuring electrodes. The first measuring electrode is at least partly covered by a porous material open to diffusion of the particles to be determined.
