Non-destructive testing

High-tech materials and modern structures are often the driving force behind industrial product developments, therefore paving the way for a wide range of innovations. However, the development and testing of such materials pose particular challenges for materials testing, as conventional non-destructive testing methods are sometimes unsuitable.

New sensor concepts, robot-assisted measurements, cloud-based methods of data acquisition and linking, and data evaluation using AI methods are driving the transformation of non-destructive testing (NDT) and material diagnostics and expanding the range of applications. Terahertz technology, in particular, will play a special role in the future: it will make it possible to measure the material thickness of multi-layer composites, for example, in a non-contact and non-destructive manner, or to analyze structures and defects in bulk materials. With several dozen measurements per second, the systems are now so fast that they can be used directly in the production line for inline testing.

Fields of research:

  • Capacitive micromechanical ultrasonic transducers (CMUT)
  • Terahertz technologies
  • X-ray analysis
