ABSTRACT:
An electrothermal sensor is shown having an electrically conductive substrate, an electrically insulating layer disposed on the substrate, a first thermistor disposed on a central region of the electrically insulating layer, a second thermistor disposed adjacent an edge of the electrically insulating layer, an electrical coupling device on the electrically insulating layer for coupling the first and second thermistors externally of the electrically insulating layer and a pair of electrical connecting devices coupled to the substrate and passing through the electrically insulating layer, the first thermistor being disposed between the pair of electrical connecting devices.
