FLEXIBLE HEATING DEVICE Russian patent published in 2021 - IPC H05B3/36 

FIELD: heating devices.

SUBSTANCE: invention relates to resistive heating devices. The technical result is achieved by the fact that the flexible heating device consists of a base (1), a conductor made of electrically conductive paint applied by airbrushing to the base, strip electrodes (2) installed on the base along the edge of the device and connected to the conductor, at least one insulating layer from the side of the base without a conductor and at least one insulating layer applied on top of the strip electrodes and the conductor, and the conductor consists of 3 sections (3,4,5) located in series from the edge to the edge of the strip, while the ratio of the average thickness (H1) of the conductor in the zone is from 0 to 20% (3) and from 80 to 100% (4) of the distance between the edges of the electrodes (L) with the average thickness (H2) of the conductor in the remaining zone (5) is 1.1-2.

EFFECT: simultaneous provision of high reliability in use and application of high operating temperatures of heating.
