Ceramic heating devices with a three-dimensional ceramic element are disclosed for protecting surfaces from icing. The shape of the three-dimensional ceramic element can be configured to physically match to the three-dimensional profile of the protected surface, allowing for high thermal coupling with the surface. The shape of the three-dimensional ceramic element can also be configured to form an aerodynamic surface typically found on the exterior of aircraft.

Ceramic heating device

A heater includes at least one heating element having a resistance that varies non-linearly with respect to a temperature of the heating element. The heating element includes a first surface, a second surface opposite the first surface, a third surface extending between the first and second surfaces, and a fourth surface extending between the first and second surfaces, opposite the third surface. The heating element has a height defined between the first and second surfaces, and a width defined between the third and fourth surfaces, and wherein the width is less than the height. The heater also includes at least one electrode coupled to the first surface and configured to generate an electric field across the heating element and cause a current to flow through the heating element.
