Abstract
Embodiments of the invention provide systems and methods for an implantable capacitive pressure sensor. Some embodiments of the invention include a capacitive pressure sensor capsule comprising a substrate, a conductive plate functionally coupled to the substrate, a conductive diaphragm spaced from the conductive plate and functionally coupled to the substrate, a lid hermetically sealed against the substrate, and pressure sensing circuitry disposed within a volume generally defined by the lid and the substrate. Embodiments of the invention also include a lead provided with an implantable pressure sensor capsule and a method of manufacturing a capacitive pressure sensor capsule.
