Abstract

See full text

Systems and associated methods place a temperature sensing element in an 'edge region' between an energy transmitting electrode and a non-electrically conducting support body, where higher temperatures are likely to exist. Reliable temperature sensing, which is sensitive to variations in temperatures along the electrode, results.
