Two-dimensional (2D) arrays were realized using a commercial 0.5-μm complementary-metal-oxide-semiconductor (CMOS) process for the EDC circuits combined with post-CMOS micromachining to pattern the comb-like probes and the corresponding electrode metallization. A dedicated CMOS integrated front-end circuit was developed for pre-amplification and multiplexing of the neural signals recorded using these probes. 2D arrays with IrOx metal finish showed electrode impedances of 300 kΩ on average with a standard deviation of 175 kΩ. In vivo tests demonstrated the capability to simultaneously record multi-unit activity in addition to local field potentials on each of the available output channels using the electronic depth control circuitry, and to finely adjust the position of the recording sites along the probe shaft for an optimal signal-to-noise ratio. In addition, this depth control concept has been demonstrated in the electronic steering of electrodes selected simultaneously within thalamic sites in the rat. By enabling the selection and thus position fine-tuning of the individual recording sites after implantation, this new device significantly increases the amount of useful information that can be obtained from a single recording experiment. © 2011 IEEE.}, keywords = {IN-VIVO; PROBES; Signal to noise ratio; In-vivo tests; Multi-channel; Local field potentials; Standard deviation; Two dimensional; Dielectric devices; MULTIELECTRODE ARRAYS; Rat control; Two dimensional (2D) arrays; Signal to noise; Post-CMOS; Output channels; New devices; Neural signals; Multiple channels; Multi-unit activity; Front-end circuits; Electronic steering; Electrode impedance; Depth control; Comb-like; 2D arrays; neural probes; multi-electrode arrays; implantable biomedical devices; Complementary-metal-oxide-semiconductor (CMOS) integrated circuits}, year = {2011}, eissn = {1940-9990}, pages = {403-412}, orcid-numbers = {Ulbert, István/0000-0001-9941-9159; Fiáth, Richárd/0000-0001-8732-2691; Kerekes, Bálint Péter/0000-0001-9542-8082} } @article{MTMT:2435429, title = {In vivo validation of microelectrode arrays with electronic depth control for acute recordings}, url = {https://m2.mtmt.hu/api/publication/2435429}, author = {Dombovári, Balázs Gábor}, journal-iso = {PÁZMÁNY PÉTER CATHOLIC UNIVERSITY PHD PROCEEDINGS}, journal = {PÁZMÁNY PÉTER CATHOLIC UNIVERSITY PHD PROCEEDINGS}, unique-id = {2435429}, issn = {1788-9197}, year = {2010}, pages = {17-20} } @inproceedings{MTMT:1992476, title = {Two-dimensional multi-channel neural probes with electronic depth control. 2010 IEEE Biomedical Circuits and Systems Conference, BioCAS 2010}, url = {https://m2.mtmt.hu/api/publication/1992476}, author = {Torfs, T and Aarts, A and Erismis, M A and Aslam, J and Yazicioglu, R F and Puers, R and Van, Hoof C and Neves, H and Ulbert, István and Dombovári, Balázs Gábor and Fiáth, Richárd and Kerekes, Bálint Péter and Seidl, K and Herwik, S and Ruther, P}, booktitle = {2010 IEEE Biomedical Circuits and Systems Conference, BioCAS 2010}, doi = {10.1109/BIOCAS.2010.5709605}, unique-id = {1992476}, abstract = {Multi-electrode arrays for in vivo neural recording are presented incorporating the principle of electronic depth control, i.e. an electronic selection of electrode locations along the probe shaft independently for multiple channels.
