  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 applications, new methods and technologies are developed, existing methods and technologies are improved, and the development of standards and technical guidelines is supported 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 emissions 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 machinery and constructions, modular sensor platforms are developed and deployed based on mobile robotics.
