SensWIRING project developed a wiring health monitoring system, WHM. The main focus was on the development of smart sensor network with defect detection functions, a low power embedded electronics, a wireless communication component and an energy harvesting and management function. The development of the sensing technology that fits into the wire harness and fulfils their measurement function properly was the main goal. Besides developing the defect sensing technology, the measurement techniques and parameters as well as the interpretation of the measurements were performed. The developed WHM was prototyped, tested and demonstrated in a laboratory environment. The SensWIRING project was a milestone in the technology for on-board WHM.
