Sensor system and method

Abstract

A sensor system includes a sensing element having a section of a layer assembly deposited onto a substrate. The layer assembly includes plural layers of different materials. The section of the layer assembly is configured to be etched to form plural individual pillars of the plural layers of the different materials. The individual pillars are configured to be in contact with a fluid to sense one or more analyte fluid components within the fluid. The sensing element is configured to generate a sensor signal responsive to the individual pillars being in contact with the fluid. The sensor system includes one or more processors configured to receive the sensor signal from the sensing element. The one or more processors may identify the one or more analyte fluid components within the fluid and an amount of each of the analyte fluid components within the fluid based on the sensor signal.
