Abstract: Transducers and processes of forming the transducers are described. The transducers are produced as a monolithic body of a ceramic material and electrodes embedded in and encased by the ceramic material, with the ceramic material and the electrodes being co-fired to produce the monolithic body. By embedding the electrodes in the ceramic material, the ceramic material protects the electrodes and isolates the electrodes from the environment, eliminating or reducing the need for separate sealing or potting material to isolate the electrodes from the surrounding environment. In addition, unique transducer designs can be produced, and the electrodes can have configurations and can be located in the transducer in locations that are not possible with traditional transducer production techniques.
