Abstract: A battery pack having a housing, at least a first battery cell in the housing, and at least one expansion sensor. An outer shell of the first battery cell has an electrically conductive material. The sensor is arranged between the electrically conductive material and an abutting surface adjacent to the first battery cell and includes at least one flat inductor circuit arranged on a flexible substrate. The flat inductor circuit is arranged in a contact zone between the first battery cell and the abutting surface, with at least a first compressible buffer layer arranged between the flexible substrate and the electrically conductive material of the outer shell and a detection circuit coupled to the flat inductor circuit via connector lines arranged on the flexible substrate for detecting a change in inductance of the flat inductor circuit.

Abstract: A method of producing an assembly of structured members comprises: providing a flat substrate from plastic material; printing on the substrate tracks of a first thickness and corresponding to an intended course of the structured members from a material with strong adherence (AD1, AD2) to both the plastic material substrate and the electrically conductive material; printing a masking material with the first thickness directly on the surface, the masking material having an adherence (AD4) to the plastic material substrate that is larger than an adherence (AD3) to the electrically conductive material, wherein AD1 is larger than AD3; applying an atmospheric plasma spray process to cover each of the tracks and a portion of the masking material adjacent each respective track with the electrically conductive material; and applying a cleaning process to remove the electrically conductive material from at least the portion of the masking material adjacent to each respective track.
