1. A sensor package comprising:
a non-conductive substrate;
at least two electrically conductive coils located at a first side of the non-conductive substrate;
an evaluation circuit located at a second side of the non-conductive substrate opposing the first side of the non-conductive substrate; and
conductive connections between the at least two electrically conductive coils and the evaluation circuit,
