Ferrous component

Abstract

Disclosed is a ferrous component comprising a ferrous layer (10) that is disposed between two electrodes (12, 13), a thin-film field-effect transistor (4) whose gate electrode (3) forms one of the two electrodes (12, 13) of the ferrous layer (10) which is joined to the gate electrode (3) via an intermediate layer (11) acting as an adhesive, and a substrate that is used as a support. In order to obtain a flexible component, the thin-film field-effect transistor (4) and the ferrous layer (10), which is composed of an internally loaded cellular polymer, are applied to the substrate that is embodied as a flexible plastic film (1) while an insulating layer (2) is optionally placed therebetween.
