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.

Abstract: There is provided a sensor device, a sensor module, and methods for determining a position of a light source. The sensor device comprises a plurality of sensor units, each sensor unit having a respective sensor area. The sensor device also comprises a mask disposed above the plurality of sensor units and arranged such that incident light from the light source will illuminate different regions of the sensor area of each one of the sensor units depending on the position of the light source relative to the sensor device. The position of the light source may therefore be determined based on which regions of the sensor area of the sensor units are illuminated. Further, each sensor unit is arranged to be controlled by a respective unit controller to determine the position of the light source.
