The measurement technology group's activities are focused on mainly two areas, ultrasound for biomedical applications and high-power ultrasound for process intensification.
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 processes. Together with the division for technical acoustics, we have shown by using cooperating resonant structures that the technology has positive effects on the efficiency of chemical processing such as mineral leaching. The research is now focused on methods for optimizing physical intensification processes.
