Abstract
In some embodiments, an implantable microelectrode is provided with a shank comprised of a laterally extending platform whose thickness and/or configuration contributes to reduced tissue encapsulation, with at least one electrode site disposed at least partially on or in the laterally extending platform. Novel methods of designing, making, and using an implantable microelectrode or biosensor resulting in reduced tissue encapsulation are also disclosed.
