Abstract:
1. A measuring apparatus comprising: one or more coplanar conductor patterns, wherein each of the coplanar conductor patterns has a rectangular side surface and a flat top surface, and each of the flat top surfaces of the coplanar conductor patterns is at a same vertical level; a measuring device configured to measure an impedance produced by an electrical connection between the one or more coplanar conductor patterns and a corresponding conductor pattern environment; and a capacitor-based adaptor connected in series between the measuring device and the one or more coplanar conductor patterns and configured to adapt the impedance produced by the electrical connection to the measuring device, wherein a measuring range of the measuring device, without the capacitor-based adaptor, is outside a range of impedance produced by the electrical connection, wherein the capacitor-based adaptor is adapted to fit the impedance produced by the electrical connection to the measuring device, and wherein the impedance produced by the electrical connection is measured by the measuring device to monitor a strength of the electrical connection in the one or more coplanar conductor patterns, and detect at least one object within a proximity of the one or more coplanar conductor patterns.
