AU-BB/EMI SENSOR NOD · Concept, design and prototyping of compact sensor nodes using electromechanical impedance and broad band acousto-ultrasonic method for structural health monitoring

In the course of the project compact sized, rugged network enabled sensor nodes for monitoring structural health using • Electro mechanical impedance method (EMI) • Broadband acousto ultrasonic method (AU-BB), will be designed (embedded hard- and software) and prototypes manufactured. A cost-efficient but still failure tolerant network interface will enable the sensor node to operate in a heterogeneous multi-sensor environment keeping wiring complexity and thus weight and cost low. The approach respects the high level of EMC that is required in aviation. A first processing of the sensor signal will take place on the node to significantly reduce network load and keeping necessary performance of a data collecting master node low. A dedicated software framework will enable the insertion of automatically generated code.
