| The photoresist SU-8, often used in microtechnology, has been acoustically characterized at a frequency of 1 GHz thanks to thin-disk piezoelectric ZnO transducers. Acoustical characterization of SU-8-based nanocomposites made of SU-8 and nanosize TiO2 and/or SrTiO3 particles is presented. These nanocomposite materials would be used to achieve acoustical matching between silicon and water at a frequency of 1 GHz and of application for the integration of high frequency ultrasonic transducer in Lab-on-Chip for biological cell characterization. |
