Potential Energy surface sensor chip and use of potential energy surfaces on a sensor chip and method for preventing a sensor chip from being soiled

摘要

In the case of sensor chips according to the prior art, due to the contaminants in the medium of the flow sensor chip grazed standing a precipitate occurs in the sensor area.; Sensor chip (1) according to the invention comprises at least one potential surface (44, 47, 50, 53) toward the direction of flow upstream of at least the sensor area 17, the contaminants and electrically in the potential surface is the fluid medium by interacting, to prevent the sedimentation in the sensor area 17.
