1. An implant comprising:

  • a wireless implant housing that defines a cavity;

    a sensor connected to said wireless implant housing comprising;

    a diaphragm having at least one diaphragm electrode;

    a base attached directly to a surface of the diaphragm, the base includes at least one base electrode, wherein said base and said diaphragm define a capacitive gap between the at least one diaphragm electrode and the at least one base electrode, wherein the base is made from a non conductive material; and

    wherein said base is directly attached to said diaphragm along an attachment configuration, wherein said attachment configuration includes a discontinuity through which at least one electrical trace connects at least one electrical contact outside of said capacitive gap to the at least one diaphragm electrode and/or the at least one base electrode, and wherein said discontinuity is a vent to allow the passage of fluid or gas between the cavity and the capacitive gap.
