1. An addressing circuit for a conductor array comprising intersecting row and column conductors, wherein the addressing circuit comprises:
a switching circuit configured to selectively address an intersection between a selected row conductor and a selected column conductor for connection to a measuring circuit; and
at least one voltage buffer selectively connectable to un-selected column conductors on opposite sides of and adjacent to the selected column conductor;
wherein the at least one voltage buffer is configured to equalise voltages between the un- selected column conductors and the selected column conductor.
