A thin film heater includes at least two open regions formed along each of two spaced-apart edges of the thin film material, which edges are parallel to two spaced-apart edges of the underlying substrate. The open regions expose areas of underlying substrate. When electrical power is coupled to the two spaced-apart edges of the thin film material, uniformity of the heat generated across the thin film material is enhanced. The substrate may be planar or curved, and the open regions in the thin film material may be removed from deposited thin film material, or may be formed by preventing deposition of thin film material in such regions.

Structure and method to compensate for thermal edge loss in thin film heaters

A resistance heater for heating fluids including a fluid-permeable porous substrate. An electrically conductive porous thin film is deposited on the porous substrate. An electrical connector coupled to the thin film and adapted to provide an electrical circuit through said thin film to effect heating of said thin film in order to heat a fluid passing through the pours of the thin film and substrate. A method of making and using a resistance heater is also disclosed.
