dc.description.abstractTwo years of polyimide based electrode structure implantation into the rabbit eye showed spatial features of local swellings and peeling off nearby electrode sites. In case of swelling and peeling off, it causes serious gradual deteoriation of polyimide structure and result in functional failure for electrode.
We suggest a reinforced structure with chemical, mechanical oxygen plasma treatment and geometrical grid design to prevent from swelling or peeling off of polyimide layer.
To show the effect of these structural modification, we introduced a reliability test method of layer adhesion, blister test. Designed samples were soaked into phosphate buffered saline(PBS) for accelerated aging study.
In this study, such a reinforcement showed an effectiveness of water absorption barrier and longer preservation of structure compared to a non-treated structure.
