Sensors based on this principle feature a band gap covering the typical input span of the measurand as well as a narrow transmission peak within the band gap where the frequency of maximum transmission is governed by the measurand. This approach has been applied for determination of volumetric properties of liquids (Lucklum et al. in Sens Actuators B Chem 171-172:271-277, 2012; Oseev et al. in Sens Actuators B Chem 189:208-212, 2013; Lucklum and Li in Meas Sci Technol 20(12):124014, 2009) and has demonstrated attractive sensitivity. One way to improve sensitivity requires higher probing frequencies in the range of 100 MHz and above. In this range surface acoustic wave (SAW) devices are an established basis for sensors. We have performed first tests towards a PnC microsensors (Lucklum et al. in Towards a SAW based phononic crystal sensor platform. In: 2013 Joint European frequency and time forum and international frequency control symposium (EFTF/IFC), pp 69-72, 2013). The respective feature size of the PnC SAW sensor has dimensions in the range of 10 µm and below. Whereas those dimensions are state of the art for common MEMS materials, etching of holes and cavities in piezoelectric materials that have an aspect ratio diameter/depth is still challenging. In this contribution we describe an improved technological process able to realize considerably deep and uniform holes in a SAW substrate.}, language = {en} } @inproceedings{FominaKoshuroFominetal.2016, author = {Fomina, Marina A. and Koshuro, Vladimir A. and Fomin, Aleksandr A. and Rodionov, Igor V. and Skaptsov, Aleksandr A. and Zakharevich, Andrey M. and Aman, Alexander and Oseev, Aleksandr and Hirsch, S{\"o}ren and Majcherek, Soeren}, title = {Peculiarities of structure formation of layered metal-oxide system Ti-Ta-(Ti,Ta) x O y during electro-spark alloying and thermally stimulated modification}, series = {Konferenz: Saratov, Russian Federation/ Titel: PROCEEDINGS VOLUME 9917 SARATOV FALL MEETING 2015 | 22-25 SEPTEMBER 2015 Saratov Fall Meeting 2015: Third International Symposium on Optics and Biophotonics and Seventh Finnish-Russian Photonics and Laser Symposium (PALS)}, booktitle = {Konferenz: Saratov, Russian Federation/ Titel: PROCEEDINGS VOLUME 9917 SARATOV FALL MEETING 2015 | 22-25 SEPTEMBER 2015 Saratov Fall Meeting 2015: Third International Symposium on Optics and Biophotonics and Seventh Finnish-Russian Photonics and Laser Symposium (PALS)}, editor = {Tuchin, Valery V. and Derbov, Vladimir L. and Postnov, Dmitry E. and Meglinski, Igor V. and Larin, Kirill V. and Pravdin, Alexander B. and Genina, Elina A.}, publisher = {SPIE.
