Oxygen transfer properties of ion-implanted yttria-stabilized zirconia [PDF]

, 1992
The influence of surface modification by ion implantation on oxygen transfer in yttria-stabilized zirconia (YSZ) has been studied. Implantation of 15 keV 56Fe in YSZ with a maximum dose of 8×1016 atoms cm−2 yields reproducible surface layers of ...

Modeling intracranial electrodes. A simulation platform for the evaluation of localization algorithms

Frontiers in Neuroinformatics, 2022
IntroductionIntracranial electrodes are implanted in patients with drug-resistant epilepsy as part of their pre-surgical evaluation. This allows the investigation of normal and pathological brain functions with excellent spatial and temporal resolution ...

Accuracy and Workflow Improvements for Responsive Neurostimulation Hippocampal Depth Electrode Placement Using Robotic Stereotaxy

Frontiers in Neurology, 2020
Background: Robotic stereotaxy is increasingly common in epilepsy surgery for the implantation of stereo-electroencephalography (sEEG) electrodes for intracranial seizure monitoring. The use of robots is also gaining popularity for permanent stereotactic

Grip control and motor coordination with implanted and surface electrodes while grasping with an osseointegrated prosthetic hand

Journal of NeuroEngineering and Rehabilitation, 2019
Background Replacement of a lost limb by an artificial substitute is not yet ideal. Resolution and coordination of motor control approximating that of a biological limb could dramatically improve the functionality of prosthetic devices, and thus reduce ...

Implantation and reimplantation of intracranial EEG electrodes in patients considering epilepsy surgery

Epilepsia Open, 2023
In patients with drug‐resistant epilepsy who are considering surgery, intracranial EEG (iEEG) helps delineate the putative epileptogenic zone. In a minority of patients, iEEG fails to identify seizure onsets.

Multilayer 3D electrodes for neural implants [PDF]

Journal of Neural Engineering, 2019
In many applications, multielectrode arrays employed as neural implants require a high density and a high number of electrodes to precisely record and stimulate the activity of the nervous system while preserving the overall size of the array.Here we present a multilayer and three-dimensional (3D) electrode array, together with its manufacturing method,
