Flexible and stretchable heating based on a conductive textile or a conductive polymer foam

摘要

An electrical heating device (10), in particular for motor vehicle use, comprises at least one heating element (12) and electrical connections (20, 22), which are provided as electrical connections that can be connected to an electrical power supply. The electrical heating element (12) has at least one dielectric, planar, flexible carrier (14), which is designed as a textile carrier or as a polymer foam carrier, and has an upper surface (16) and an opposite lower surface which is parallel to the upper surface ( 16), wherein at least one of the upper surface (16) and the lower surface is provided with an attached continuous layer of an electrically conductive material (18) which extends over a larger part of an area of the respective surface (16) of the at least one flexible carrier (14) extends. At least one electrical connection (20, 22) is arranged at each end of the electrically conductive material layer (18) of each heating element (12) and is electrically connected to it.
