System and method for inspection of rotating or buried elements

System for inspection of rotating or buried elements, comprising:

• a flexible sensor band,
• whereby the flexible sensor band comprises a first sensor arrangement for detecting mechanical stress at the rotating or buried element,
• whereby the flexible sensor band comprises a second sensor arrangement for detecting humidity at the rotating or buried element,
• whereby the flexible sensor band further comprises an energy harvesting section,
• whereby the flexible sensor band further comprises a wireless communication section, the wireless communication section being adapted to transmit data relating to the detected mechanical stress of the first sensor arrangement and a unique ID relating to the first sensor arrangement towards a receiving section, whereby the wireless communication section is further adapted to transmit data relating to the detected humidity towards said receiving section, wherein the receiving section being arrangeable at a position such that the flexible sensor band when the rotating or buried element is passing the receiving section may transmit the data towards the receiving section,
• whereby the flexible sensor band comprises nano-particles, in particular carbon-nano-particles, within the first sensor arrangement,
• whereby the flexible sensor band comprises an epoxy resin and/or thermoplastic or thermoset polymer,
• whereby the wireless communication section is a near field communication system,
• whereby the sensor band further comprises a memory for storing data,
• whereby the sensor band further comprises a processing entity for processing data of the sensor arrangement before transmission,
• whereby the energy harvesting section is based on at least one of vibration, rotation or reception of electro-magnetic fields,
• whereby the sensor band is at least in part manufactured by a screen printing process,
• whereby the flexible sensor band comprises a third sensor arrangement for detecting temperature at the rotating or buried element, whereby the wireless communication section is further adapted to transmit data relating to the detected temperature and/or humidity towards said receiving section,
• whereby the flexible sensor band having at least one adhesive surface for attaching on a rotating or buried element, and
• whereby the flexible sensor band is dissolved within a rotating or buried element leaving the first sensor arrangement and the second sensor arrangement as well as the wireless communication section embedded within the rotating or buried element.
