Abstract
The invention relates to a sensor for a physical feature, comprising a structure, preferably a multilayer structure, comprising: at least one electrically conductive layer, comprising nanofillers in a polymer matrix including at least one polymer, and electrical connection means, said structure being thermosetting, thermoplastic, or being a cross-linkable elastomer, characterised in that, when the structure is thermosetting, the degree of cross-linking thereof is higher than 80%, better still higher than 90%, or even 95%; when the structure is a cross-linkable elastomer it includes an amount of cross-linking agent ranging from 5 mol. % to 20 mol. % relative to the number of moles in the structure; and when the structure is thermoplastic, it has a constant resistivity value and preferably a degree of crystallinity ranging from 0% to 60%.
