  6. Sensors, Measurement and Testing Methods

The Sensors, Measurement and Testing Methods division deals with tasks related to non-destructive testing, in order to ensure that materials, products, machinery and systems are safe and fit for purpose. Specifically, sensors and measurement methods are applied to practical applica-tions, new methods and technologies are developed, exist-ing methods and technologies are improved, and the de-velopment of standards and technical guidelines is sup-ported to this end.

Sensor and measurement technology-based methods are preferentially used for tasks in relation to condition moni-toring (monitoring, structural health monitoring [SHM]), early damage detection, experimental stress analysis, ma-terial characterisation and also environmental and emis-sions monitoring.

The development of multifunctional materials and self-monitoring components/structures by means of sensor technology integrated into the materials is also part of the division's activities. For large-scale condition recording and monitoring, for instance for process and geotechnical ma-chinery and constructions, modular sensor platforms are developed and deployed based on mobile robotics.
