Latest Patents

Stegemann's latest patents include "Tensile acoustic rheometry for characterization of viscoelastic materials" and "Resonant acoustic rheometry for characterization of soft viscoelastic materials." The first patent introduces a new acoustic technique called tensile acoustic rheometry (TAR). This method utilizes a focused ultrasound transducer to apply an excitation acoustic pulse to a soft viscoelastic material sample, inducing oscillatory motion. High repetition frequency ultrasound pulse-echo techniques are employed to track this motion, allowing for the determination of viscoelastic properties based on displacement and spectrogram measurements.

The second patent focuses on resonant acoustic rheometry, which involves two sets of acoustic pulses to measure surface oscillations of the sample. The detection transducer captures echo pulses reflected by the sample surface, converting them into electrical signals. A processor analyzes these signals to determine dynamic displacement, resonant surface oscillation frequency, and damping coefficient. This technique has applications in characterizing blood clotting processes, identifying blood clots, and assessing tumor or fibrosis conditions based on viscoelastic properties.
