1. A composite electrode comprising:
- a plurality of ceramic elements, each of the ceramic elements having (a) a lower surface configured to rest on a patient'"'"'s body and (b) an upper surface;
a first lead;
at least one electrical conductor configured to make a direct electrical connection between the upper surface of each of the ceramic elements and the first lead; and
a support structure configured to mechanically connect the plurality of ceramic elements during use, with the lower surface of each of the plurality of ceramic elements resting on the patient'"'"'s body.

Abstract
An electrode for applying electric fields to a patient includes a plurality of ceramic elements (e.g., ceramic discs) that are designed to be positioned against the patient'"'"'s skin. Electrical connections are made to the ceramic elements (e.g., using a flex circuit). Temperature sensors (e.g., thermistors) are preferably provided at at least some of the ceramic elements to sense the temperature at the skin beneath the ceramic elements, so that appropriate action can be taken if an overtemperature condition is detected.

13. A composite electrode comprising:
-
at least four ceramic elements, each of the ceramic elements having (a) a lower surface configured to rest on a patient'"'"'s body and (b) an upper surface; a first lead; at least one electrical conductor configured to make a direct electrical connection between the upper surface of each of the ceramic elements and the first lead; and a support structure configured to mechanically connect the ceramic elements during use, with the lower surface of each of the ceramic elements resting on the patient'"'"'s body; at least two temperature sensors configured to sense the temperature beneath at least two of the ceramic elements, respectively; a layer of electrically conductive hydrogel disposed on the lower surface of each of the ceramic elements; a covering disposed above the ceramic elements and the support structure, the covering having an adhesive lower surface that is configured to hold the ceramic elements and the support structure against the patient'"'"'s body. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27)
