ABSTRACT:
A circuit includes i sensors interconnected in an (n×m) matrix circuit with n row conductors and m column conductors, where i, n, and m are natural numbers different than zero and where 1≦i≦n×m, each of the n row and m column conductors include a first and a second conductor end. The first conductor end of the n row conductors and the m column conductors is connectable to an evaluation circuit, and each of the i sensors are connected between two respective conductors from the n row and the m column conductors. A first conductor end of an at least one return conductor is connectable to the evaluation circuit and a second conductor end of the at least one return conductor is in contact with the second conductor end of one of the n row conductors or one of the m column conductors.
