Abstract
A heating element and fluid pump including that heating element. The heating element for a fluid pump comprises a substrate, preferably made of glass, in particular quartz glass, or ceramics, a thin layer of monocrystalline, polycrystalline or amorphous material provided on top of the substrate, and electrical contacts provided in contact with the thin layer, preferably made of conductive ink or an electrically-conductive paste, wherein the thin layer has a thickness equal to or smaller than 10 μm.

A fluid pump comprising:
- a fluid pump casing having a cylindrical body portion;
- a pump chamber inside the fluid pump casing and defined by an outer wall, a bottom part, a top part, an inlet, and an outlet;
- a heat reflector made of metal and located on an inner wall of the cylindrical body portion of the fluid pump casing, the heat reflector protecting the fluid pump casing;
- a heating element comprising:
- a substrate made of an insulative material and comprising a first axial end and a second axial end, wherein the substrate has a cylindrical shape and forms the outer wall of the pump chamber;
- a thin layer of monocrystalline, polycrystalline, or amorphous material on the substrate;
- and
- electrical contacts being in contact with the thin layer,
- wherein the thin layer has a thickness equal to or smaller than 10 μm, and
- wherein at least the first axial end or the second axial end of the substrate comprises a region that remains uncovered by the thin layer and configured for coupling to another device,
- wherein the thin layer faces, in a radial direction, the heat reflector,
- wherein the heating element forms at least a portion of the outer wall of the pump chamber, and
- wherein the fluid pump further comprises at least one control and safety unit on a contact layer, and the contact layer is on the region that remains uncovered by the thin layer.
