A method for electrically contacting a piezoelectric ceramic includes: providing the piezoelectric ceramic having electrodes for electrically contacting the piezoelectric ceramic and having a flexible, electrically conductive film; producing a composite by applying the flexible, electrically conductive film at least partially to an electrode of the piezoelectric ceramic; forming a durable, electrically conductive connection between the flexible, electrically conductive film and the electrode of the piezoelectric ceramic. Also a sound transducer, as well as a sound transducer array produced using the method for electrically contacting a piezoelectric ceramic.

Process for tuning a magneto-resistive sensor

An apparatus for measuring small displacements, either linear or angular, employ a pair of spaced 'barber pole' or other magnetic field sensitive elements and a movable magnet, in which the exact position of the movable magnet is determined from the voltages sensed at the two elements. The voltages are evaluated in a circuit which produces a rectangular voltage or equivalent, in which the mark/space ratio equates to the position of the magnet between the two sensors.
