A structural body which, at least region-wise, has at least one area which is in contact with a liquid or a gas flowing past, and which, at least to a great extent, is provided with a surface patterning made of a plurality of randomly or irregularly distributed geometric forms, in particular pyramids. At least one such structural body be used in a capacitive sensor with which, in particular, the dielectric constants or the conductance of a liquid or a gas can be determined.
