Decoder for determining a substance or material structure of a detected object based on signals of a capacitive sensor and method for determining a substance or material structure of a detected object based on signals of a capacitive sensor

摘要

A decoder unit for determining a substance or material structure of a detected object based on signals of a capacitive sensor comprises a distribution determination device arranged to determine a detected distribution relation based on signals of the at least one capacitive sensor; a comparison device arranged to compare the detected distribution relation with at least one predetermined distribution relation, the at least one predetermined distribution relation corresponding to a substance or a material structure and an output device arranged to indicate the result of the comparison carried out by the comparison device.
