Abstract (en)
[origin: EP1201322A2] The method involves producing ceramic elements as piezoelectric or electrostrictive rods (20) with a constant thickness plastic coating, feeding them to a container (31) with a vibration drive to pack them vertically, filling the container with plastic, resin or polyurethane, removing the container after setting, grinding until the rods are at a length suitable for a working frequency and arranging electrodes to contact some or all rods. Independent claims are also included for the following: an ultrasonic transducer.
