Biography

Anna Pak was born in Karaganda, Kazakhstan. She received her B.Sc. degree in nanotechnology from Novosibirsk State Technical University (Russia) in 2015 and the M.Sc degree in nanobiophysics from TU Dresden (Germany) in 2017. Later she continued working in the lab of Dr. Minev (BIOTEC, TU Dresden) on the development of 3D printed soft optical fibers and microfluidic channels for implantable devices.

Her current research interest is in soft bioelectronics with the main focus on material and technology development for integration in neuroprosthetics.

    Abstract: ... This work aims to develop a smart neural interface with transparent electrodes to allow for electrical monitoring of the site of interest during optogenetic stimulation of the spinal cord. In this paper, a microfabrication process for the wafer-level development of such a compact, active, transparent and flexible implant is presented. Graphene has been employed to form the transparent array of electrodes and tracks, on top of which chips have been bonded using flip-chip bonding techniques. To provide high flexibility, soft encapsulation, using polydimethylsiloxane (PDMS) has been used. Making use of the "Flex-to-Rigid" (F2R) technique, cm-size graphene-on-PDMS structures have been suspended and characterized using Raman spectroscopy to qualitatively evaluate the graphene layer, together with 2-point measurements to ensure the conductivity of the structure. In parallel, flip-chip bonding processes of chips on graphene structures were employed and the 2-point electrical measurement results have shown resistance values in the range of kΩ for the combined tracks and ball-bonds.
