Screw connections on critical infrastructures are exposed to major stresses and must therefore be checked on a regular basis. Researchers at the Fraunhofer Cluster of Excellence Cognitive Internet Technologies CCIT have now developed a technology that allows the stability of the screw connections to be checked at any time by remote monitoring. This increases safety and reduces the time and effort spent on inspections.
