Cylindrical cochlear electrode array for use in humans.
TLDR
In vitro and in vivo tests are ongoing with good results so far and the fabrication of a flexible multichannel electrode array suitable for use in humans is described.Abstract:
This report describes the fabrication of a flexible multichannel electrode array suitable for use in humans. The conductors, pads, and stimulating tips are made of platinum on a polyimide substrate. Photolithographic techniques are employed in the fabrication of the electrode on a planar surface in the form of a film. The film is rolled subsequently into a cylinder of diameter 0.50 mm and the cylinder is filled with medical grade silicone rubber. The stimulation pads then form rings around the cylinder. In vitro and in vivo tests are ongoing with good results so far.read more

Electrical Stimulation with Pt Electrodes: II-Estimation of Maximum Surface Redox (Theoretical Non-Gassing) Limits
S. B. Brummer,M. J. Turner +1 more
TL;DR: The maximum, biphasically applied charge which can be injected without electrolyzing water has been determined for Pt electrodes in simulated cerebral spinal fluid at 37°C, and microscopic observations of bubble formation indicate that these limits are conservative.
