Profile
The working group "Sensors and Ultrasonics" is part of the Institute of General Physics in the
Faculty of Physics ("Fakultät für Physik") of the Vienna University of Technology.
The group is currently performing research in the following areas:
. Development of sensors and specialized measurement equipment, in particular of
frequency-output sensors utilizing Bulk Acoustic Wave (BAW) piezoelectric
resonators, for, e.g., the determination of fluid properties, such as density, viscosity
and speed of sound
. Development of capacitance ultrasonic transducers for high operating temperatures
. Development of an ultrasonic-based mass-flow meter for harsh environment
applications
. Investigation of failure mechanisms of rolling bearings due to the passage of electric
current
. Application of MHz ultrasound fields in infrared spectroscopy to avoid the formation
of biofilms on diamond surfaces and in Raman spectroscopy to concentrate biological
cells in the image plane of the device
. Investigation of adsorption processes (e.g., adsorption of polymers at fluid interfaces)
by means of the quartz crystal microbalance measuring principle
. Separation of suspended particles and biological cells by use of ultrasonic resonance
fields
. New applications of ultrasound in technology and biomedical sciences
