The invention relates to a hose having at least one barrier layer inner layer and an outer layer, wherein the barrier layer is obtainable by extrusion of a mixture comprising a) at least one thermoplastic fluoropolymer, b) at least one fluororubber and a crosslinking agent and/or at least one fluororubber elastomer and c) at least one carbon filler selected from carbon black, in particular conductivity carbon black, graphene, carbon nanofillers, in particular carbon nanotubes, carbon nanohorns, or a combination thereof in an amount of 0.05% by weight to 20% by weight of the carbon filler(s), or irradiated PTFE, and vulcanization. The hose exhibits a high fuel, diesel and oil stability and dynamic capability.

The invention relates to a sensor as a built-in component of an object, especially an elastic object, the sensor comprising a polymer material containing electroconductive additives according to the invention and thereby acting as an expansion sensor (), in that it measures the static and dynamic expansions of the object in relation to the acting forces and also monitors the changes of the polymer material generated by the static and dynamic expansions of the object over time. The invention also relates to a sensor arrangement () acting especially in combination with the following components: an expansion sensor (), a fixed resistor (), an analog/digital converter (), a micro-controller comprising a memory (), a radio interface (), a controlled current/voltage source (), an energy supply (), a coupling coil (), and a receiving unit ().
