Measurement technology

Published: 7 October 2020

The measurement technology group's activities are focused on mainly two areas, ultrasound for biomedical applications and high-power ultrasound for process intensification.

Measurement technology at LTU has long traditions and is conducted in various forms at two departments. At the research group of Electronics Systems research in measurement technology has largely been based on ultrasound with various application areas, ranging from flow measurement to photoacoustic tomography in inhomogeneous media.

In biomedicine, the activities are focused on thin 2D sensor arrays with associated electronics. The next step is to miniaturize the technology and instead use piezoelectric microelectromechanical arrays, PMUTs, where electronics for control, transmission, reception and signal processing are integrated close to the array.

Ultrasound with significantly higher power is used for process intensification in various chemical or physical process flows. Together with the division for technical acoustics, we have shown by using ultrsound driven, cooperating resonant structures that the technology has positive effects on chemical processes such as mineral leaching. The research is now focused on methods for optimizing physical intensification processes.
