Abstract:
The paper presents the results of investigations of polymer coatings used as capsules for implantable microelectronic devices for medical applications. Such devices work in artificial pacemakers and as feeding systems, in nerve ending stimulator sets. Biocompatible and biostable polysulfone capsules for integrated circuits and batteries have been prepared. Preliminary investigation of overall chemical stability of encapsulated electronic devices in Ringer's solutions, has been carried out as a function of immersion time. Influence of number of coating polysulfone layers on voltage-stability of batteries immersed in 0.9% NaCl solution has been measured with time. A comparative study of silicone (SIL) coating and double coating with silicone and polysulfone (SIL + PSU) in an in vitro test has been carried out.
