[Coating material of parlene C as encapsulation material for biomedical micro-implants].

Biomedical microsystems attain to contact with environments like blood, ephitHelium and saline solutions therefore they need an encapsulation. Parylene seems to be a suitable polymer to cover the implants and protect them against moisture and aggressive environment. This paper describes the characterisation of Parylene C coatings and its possibilities to protect implants. Beside the encapsulation of biomedical microsystems the manufacturing of fexible electrodes and the cytotoxicity behavior of RIE etched Parylene layers was investigated.
