Implantable sensor assembly including a sensor and a compliant structure

Abstract

An implantable sensor assembly comprises a support structure including a board, a compliant structure disposed on a top surface of the board, and a sensor supported by the compliant structure above the top surface of the board. An aperture is formed in the support structure for exposing at least in part a face of the sensor. The sensor may be a pressure sensor having a sensing membrane exposed through the aperture formed in the support structure. A stiffener, which may be conductive, may be mounted to a bottom surface of the board. The sensor and other components may be covered by a polymer shell having a conductive cover or by a gel contained within a rigid cap, which may be conductive. An electromagnetic shield may be formed by an electrical connection between the conductive cover or the conductive rigid cap and the conductive stiffener.
