Abstract

A new parylene-based microfabrication process is presented for neural recording and drug delivery applications. We introduce a large design space for electrode placement and structural flexibility with a six mask process. By using chemical mechanical polishing, electrode sites may be created top-side, back-side, or on the edge of the device having three exposed sides. Added surface area was achieved on the exposed edge through electroplating. Poly(3,4-ethylenedioxythiophene) (PEDOT) modified edge electrodes having an 85-μm(2) footprint resulted in an impedance of 200 kΩ at 1 kHz. Edge electrodes were able to successfully record single unit activity in acute animal studies. A finite element model of planar and edge electrodes relative to neuron position reveals that edge electrodes should be beneficial for increasing the volume of tissue being sampled in recording applications.

  • Implantation of functionalized devices demonstrated improved recording quality from electrode sites positioned on the lattice edge compared with the faces, verified through computational modeling.

    From Regenerative Electrode Interfaces for Neural Prostheses. (2016) · cites this paper as [67]

    In §3.5 (Neural recordings), acute animal recordings yielded more isolatable units and higher signal amplitudes at edge electrodes than at planar sites. The finite-element model in §3.4 supports a wider viewing angle for edge electrodes, but finds planar electrodes more sensitive when directly facing a neuron; it does not verify an across-the-board improvement in recording quality.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
