A planar heating element comprising a PTC resistive structure, which is arranged in a defined surface region of a first surface of a support substrate. The electrical connection contacts for connection to an electrical voltage source are associated with the PTC resistive structure, wherein the PTC resistive structure&#x2014;starting from the two electrical connection contacts&#x2014;has at least one internal conductive trace and a parallel connected, external conductive trace. The internal conductive trace has a greater resistance than the external conductive trace and the resistances of the internal conductive trace and external conductive trace are so sized that upon applying a voltage an essentially uniform temperature distribution is present within the defined surface region.

Planar heating element with a PTC resistive structure

The present disclosure relates to a thin film sensor element for determining and/or monitoring temperature. For this purpose, a resistive structure is provided, which is arranged in a resistive region on a substrate. The resistive structure is so formed that a first section of the resistive structure branches at a first reference point into two branches, and that a second section of the resistive structure branches at a second reference point into two other branches. In a contact region, the four branches are connected with four intermediate conductors in four contact areas, which are insulated from one another. In this way, the thin film sensor element is a real four conductor sensor element, wherein the reference points of the four conductor circuit lie within the resistive region. The resistance thermometer with the thin film sensor element of the invention is distinguished by a high accuracy.

Thin film sensor element for a resistance thermometer

An electrically heated aerosol-generating device is provided, including a heating assembly configured to heat an aerosol-forming substrate to generate an inhalable aerosol, the assembly including a heater and a heater mount, the heater being blade-shaped, including an electrically insulating heater substrate, an electrically resistive heating element supported by the heater substrate, and a through-hole through a thickness of the heater, the heater being insertable into the aerosol-forming substrate and having a length of about 10 mm to about 60 mm, a width of about 2 mm to about 10 mm, and a thickness of about 0.2 mm to about 1 mm, the mount including a moldable material molded around a portion of the heater and extending through the through-hole to couple the heater to the mount so the mount provides structural support to the heater and is configured to allow the heater to be disposed within the device.
