Tubes with Special Electrodes

Quartered outer electrodes

Wrap-around contact

Tube actuators can be provided with multi-segmented electrodes, to influence the oscillation characteristics. With wrap-around electrodes, electrical contacting can be established at a favorable position within the mechanical assembly.
