This study evaluates the long-term stability of silicone-encapsulated CMOS ICs in biofluid environments through 4.3 years of accelerated life testing, finding no insulation failures and limited failures at wire bonds.

The paper evaluates the long-term stability of implantable silicon-ICs, showing that PDMS coating prevents degradation while bare die ICs remain electrically stable for at least a year.
