Modeling of liquid pumping via microchannels

Ainabayev A., Berdenova B., Bralts V., Hassanein A., Insepov Z., Purdue University, US

We present our finite element modeling and discuss the main principles of our water actuation technique for water transport in micron scale tubes. The effect of water flow actuation by application of surface acoustic waves [...]

A Computational Study on Detection of Ultra Small Volumes of Liquid and Solid Media in Microcavities Using Surface Acoustic Wave Devices

Senveli S.U., Tigli O., University of Miami, US

In this study, we use finite element method (FEM) analysis to show the possibility of a microsystem capable of detecting and analyzing liquid and solid media in minute amounts using surface acoustic wave (SAW) devices [...]

Amplification of Surface Acoustic Waves in Graphene Film under DC Voltage

Insepov Z., Kononenko O.V., Roshchupkin D.V., Tynyshtykbayev K., Purdue University, US

An acoustoelectric effect has been experimentally studied in a graphene film fabricated on the top of a piezoelectric crystal of the lanthanum–gallium silicate family Ca3TaGa3Si2O14 (CTGS) grown by the Czochralski method. The unit-cell parameters were [...]

Numerical Computation of Dispersion Relations for Multi-layered Anisotropic Structures

Botkin N.D., Hoffmann K-H, Pykhteev O.A., Turova V.L., Center of Advanced European Studies and Research, DE

The paper presents an algorithm and a program for the computation of the propagation velocity of acoustic waves excited in anisotropic multi-layered structures. This investigation is motivated by the modeling of a biosensor that serves [...]
