Abstract
The present disclosure discusses a system and methods for a deep brain stimulation lead. More particularly, the disclosure discusses a stimulation lead that includes one or more silicon based barrier layers within a MEMS film. The silicon based barrier layers can improve device reliability and durability. The silicon based barrier layers can also improve adhesion between the layers of the MEMS film.
