Spinal cord stimulation arrays are intended to be used chronically. To increase
their stability at physiological conditions we propose to use a highlystable
material to insulate our polymericbased device. We propose to use a polymer
as the encapsulation layer, and more specifically, we are using a softening
polymer fot the interface surface area to minimize to foreign body reaction to a
stiff material, and a polyimide on the other side to provide a more robust device
at thinner dimensions. For this study we have developed a fabrication
procedure, and we have characterize our devices mechanically, electrical and
electrochemically. We have done an acceleration aging test to compare our
results to previous work withoud the insulation layer to validate our hypothesis.

I would like to show my warm thank to Dr. Voit, Dr. Cogan, and Dr. Joshi-
Imre who supported me at every bit and without whom it was impossible to
accomplish the end task.
