This photo shows Chris Kexel and me at the International Workshop on Structural Health Monitoring (IWSHM 2019) at Stanford University. We are presenting our latest research results related to SHM (guided ultrasound waves, signal processing, wind turbines, biomedical applications, imaging, ultrasound data communication).

We are very pleased to announce that a paper got accepted at the Scientific Data journal – an open access publication from the Nature Research for the descriptions of scientifically valuable datasets. Abstract: The influence of temperature is regarded as particularly important for a structural health monitoring system based on ultrasonic guided waves. Since the...

We have demonstrated a combined inspection and data communication approach for Lamb-wave Structural Health Monitoring. A paper was recently accepted for publication in IEEE Transactions on Ultrasonics, Ferroelectrics, and Frequency Control. Abstract: Guided ultrasound waves have long been studied in the context of structural health monitoring (SHM). More recently, they have also been proposed for...

A joint work on bone fracture sensing and acoustic data communication with Prof. Barker and Dr. Bhavsar (both are from Frankfurt Initiative for Regenerative Medicine, University Hospital Frankfurt) has been published in Ultrasound in Medicine & Biology. Abstract: Approximately 6.3 million fractures occur each year in the United States alone. Accurately monitoring the progression of...

The European Conference on Antennas and Propagation (EuCAP 2019) took place in Krakow (Poland). I have presented two papers at the conference: the first one was about jointed electromagnetic waveguides and the second about microwave breast cancer detection. References: Moll, J., Numerical and Experimental Analysis of Defect Detection in Jointed Electromagnetic Waveguides, 13th European Conference...

The Open Guided Waves platform has been developed to provide benchmark measurements for guided wave-based non-destructive testing (NDT) and structural health monitoring (SHM). The platform is online now and can be accessed here: http://www.open-guided-waves.de

Ultrasonic guided waves have been used successfully in structural health monitoring (SHM) systems to detect damage in isotropic and composite materials with simple and complex geometry. A limitation of current research is given by a lack of freely available benchmark measurements to comparatively evaluate existing methods. This paper introduces the extendable online platform Open Guided...

Elastic guided waves constitute a promising approach for structural health monitoring (SHM) applications involving composite structures. Guided-wave SHM systems are composed of a network of ultrasonic sensors, which are permanently attached to a structural component. Besides monitoring, the supplementary capability of the network nodes to exchange information across this mechanical wave-guide itself, represents an innovative...

Carbon fiber reinforced plastics (CFRP) are widely used in lightweight marine structures due to their high strength and superior fatigue behaviour. In this paper, we will present an innovative methodology for simultaneous load and structural monitoring of a CFRP rudder stock as part of a big commercial vessel. Experimental results are presented here from a...
