SENSOR ASSEMBLY AND POROUS MEMBRANE SENSOR ELEMENT - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240027423 titled 'SENSOR ASSEMBLY AND POROUS MEMBRANE SENSOR ELEMENT

Simplified Explanation

The present invention is a porous membrane sensor element designed to detect an analyte in a complex fluid sample. The sensor element includes a porous membrane sensor housing with a flow channel that defines an axial direction. The flow channel contains a sample space. The porous membrane has a front side that defines a sensor surface for contacting the fluid sample. The sensor surface faces towards the sample space and contains pores that extend from openings at the sensor surface into the membrane. These pores are configured to allow diffusive fluid communication with the sample space.

Additionally, the sensor element includes an optical subassembly with a light guide core. The light guide core has an input branch, an output branch, and a coupling interface that contacts the backside of the porous membrane, opposite to the front side. The input and output branches are directed towards the coupling interface and are arranged in a common light guide plane perpendicular to the sensor surface.
