The invention relates to soot sensors based on one-piece strip conductor structures, to methods for measuring soot and to the use of heat conductor chips for soot measurement. The invention is based on the sensitivity of intensive variables, especially substance-specific variables. The inventive electric soot sensor is characterized by at least one chip which is provided with at least one one-piece strip conductor comprising especially two terminal panels and by having a soot determining device that is adapted to determine an intensive or specific change of a surface. The inventive method is characterized by determining the change of an intensive variable, especially a thermospecific or electrical parameter of a chip, which change is caused by the soot deposits. |
