Coriolis Effect on elastic waves propagating in rods

Çetin, Hakan; Yaralıoğlu, Göksen Göksenin (Elsevier, 2020-10-27)

Vibration analysis of rods that are subjected to rotation is presented. It is shown that flexural-flexural, longitudinal-flexural and torsional-flexural wave coupling occur due to the Coriolis Effect. First, we carried out ...
Flexural wave-based soft attractor walls for trapping microparticles and cells

Aghakhani, A.; Çetin, Hakan; Erkoc, P.; Tombak, G. I.; Sitti, M. (Royal Society of Chemistry, 2021-02-07)

Acoustic manipulation of microparticles and cells, called acoustophoresis, inside microfluidic systems has significant potential in biomedical applications. In particular, using acoustic radiation force to push microscopic ...
Gyroscopes based on acoustic waveguides

Çetin, Hakan (2016-08)

We propose novel gyroscope architectures based on acoustic waves propagating in a waveguide. This thesis is composed of two parts. In the first part, the fundamentals of the proposed gyroscope are discussed. The new gyroscope ...
High shear rate propulsion of acoustic microrobots in complex biological fluids

Aghakhani, A.; Pena-Francesch, A.; Bozuyuk, U.; Çetin, Hakan; Wrede, P.; Sitti, M. (American Association for the Advancement of Science, 2022-03-11)

Untethered microrobots offer a great promise for localized targeted therapy in hard-to-access spaces in our body. Despite recent advancements, most microrobot propulsion capabilities have been limited to homogenous Newtonian ...
Noise analysis of mode matched vibratory gyroscopes

Çetin, Hakan; Yaralıoğlu, Göksen Göksenin (Springer, 2023-01)

MEMS (micro-electromechanical system) vibratory gyroscopes have attracted a lot of interest recently and these gyroscopes made their way through portable devices and smart phones. However, their performance is not enough ...
