Characterization of the power and thermic behaviour of an ultrasonic probe — •Tobias Löffler1, Mike Huwer1, Julia Kristin2, and Mathias Getzlaff1 — 1Institute of Applied Physics, University of Düsseldorf — 2Hals-Nasen-Ohrenklinik, Universitätsklinikum Düsseldorf
We want to use an ultrasonic probe to transfer energy to biological samples in liquid. For a better understanding of the influence of the ultrasound, we need a detailed characterization of its properties in the liquid environment.
In order to determine the temperature-profile in the vicinity of our ultrasonic probe, measurements of the temperature at different distances in direction of oscillation and additionally as a function of time have been performed. The displacement of the probe head was measured with an optical microscope.
The characterization of the output energy was performed with calibrated ultrasonic-power-detectors at different distances in the direction of propagation.
