Beschreibung
Zusammenfassung:	A hose includes a generally cylindrical tubular structure with at least one layer of steel ligaments near the outer surface, the steel ligaments being enclosed within a tubular layer including polymeric material; the flexible hose also incorporates a multiplicity of sensing coils embedded within the tubular layer, each such sensing coil being a flat coil lying in a plane substantially parallel to the adjacent layer of steel ligaments, so that an axis of the coil orthogonal to the plane of the flat coil extends in a radial direction relative to the hose. Each such sensing coil may form part of an electronic module that also incorporates a signal processing circuit and an RE power-receiving and data-transmission circuit. When that portion of the hose is subjected to an alternating magnetic field, signals from the sensing coils can be analysed to deduce information about the stress in the steel ligaments.
