Position and displacement sensor, particularly for the position and displacement of a human finger, in particular for realising an attenuator

摘要

The position sensor comprises: a conductive strip (2) on an insulating substrate (1); a resistive strip (4) on an insulating substrate (3), at least one of these two substrates being flexible, these two substrates being disposed opposite one another with (2) facing (4) a small distance away; a pair of conductors (5, 6) with ends (5a, 6a) connected to the ends of (4); and a third electrical conductor (7) with its end (7a) connected to (2).
