Abstract
A method of evaluating a dielectric structure, comprising the steps of a) changing a potential difference between each sensing structure in a first set of sensing structures and each sensing structure in a second set of sensing structures, and to providing, for each sensing structure in the first set of sensing structures, a sensing signal indicative of a strength of a capacitive coupling between each sensing structure in the second set of sensing structures and the sensing structure in the first set of sensing structures; b) assign other sensing structures to the first set of sensing structures and the second set of sensing structures; c) performing step a) and step b) until a respective sensing signal has been provided for each sensing structure in the plurality of sensing structures; and d) providing an evaluation result based on the respective sensing signals.
