Abstract

A sensor assembly for in-vivo monitoring of a body fluid or tissue (F) comprises: a pressure sensor element, comprising a micro-electromechanical system (MEMS) and arranged to detect a pressure of the body fluid or tissue (F) in use; and a shield, which generally surrounds the pressure sensor element such that the pressure sensor element is within an interior volume of the shield, in order to protect and to prevent distortion of the pressure sensor element in use. The pressure sensor element comprises a biocompatible thin film layer, for resisting corrosion and/or fouling of a surface of the pressure sensor element by the body fluid or tissue (F) or biological matter thereof. The pressure sensor element and the shield are in fixed relationship with each other.
