    摘要: A device is disclosed for filtering a particle to be detected from a fluid. In at least one embodiment, the device includes a substrate and, applied above it, a protective layer, a channel being disposed between them for the purpose of receiving a fluid containing different particles. In at least one embodiment, the channel extends at least partially in a spiral shape between its inlet and outlet and on its internal wall contains a coating for attracting a particle type to be filtered, which coating is applied at least on the radially outside subsection of the internal wall of the channel. Owing to the laminar longitudinal movement of the fluid inside the channel a radially outward directed centrifugal force acts on the particles, with the result that per time unit more particles come into contact with the radially outside subsection of the internal wall of the channel than the radially inside subsection of the internal wall of the channel. The filter effect is reinforced as a result.

    摘要: Circuit arrangement having a sensor electrode, a first circuit unit, which is electrically coupled to the sensor electrode, and a second circuit unit, which has a first capacitor. The first circuit unit holds an electrical potential of the sensor electrode in a predetermined first reference range around a predetermined electrical desired potential by coupling the first capacitor and the sensor electrode such that there is a matching of their electrical potentials. If the second circuit unit detects the electrical potential of the first capacitor being outside a second reference range, the second circuit unit brings the first capacitor to a first electrical reference potential.
