INSULATED ELECTRODE FOR DELIVERING TUMOR TREATING ELECTROMAGNETIC FIELDS

A tumor treating system for the delivery of tumor treating electric fields to a patient including a control device, a field generator, and electrodes. The control device has a frequency range, a firing configuration and a firing sequence. The field generator generates electrical signals within the frequency range. The electrodes are placed in optimized locations on the patient. Each electrode includes a ceramic layer, a metalized layer and a circuit element. The metalized layer is coupled to the ceramic layer on one side of the ceramic layer. The metalized layer has an outer surface facing away from the ceramic layer. The circuit element is coupled to the metalized layer. The coupling of the circuit element to the metalized layer is across substantially all of the outer surface of the metalized layer. The circuit element conducts the electrical signals to the metalized layer as directed by the control device.
