Abstract
- To protect electronic micro systems for medical devices speciality implants towards influences of aggressive environment and to reduce the electrochemical migration are used biomedical encapsulation materials. To research the polymers resistance during electrochemical migration was proposed the method of investigation of surface insulation resistance (SIR) of comb-electrode. The capture system consists of a common method of resistance's measuring. Investigated samples were covered with two different biomedical polymers a) Poly-Para-Xylylen of type PARYLENE C and b) silicone rubber of type MED 6–6606 and were contacted to artificial blood plasma, liquor and 0.9 % NaCl solution each in a tub. Continuously direct voltage +10 V was applied to samples. Measured data were detected every 10 minutes during first hour, every 1 hour during first 12 hours and every 12 hours during 30 days. Alteration of surface insulation resistance from time into different liquids was received and topography of samples was studied.
