Liquid Level Detection of a Blood Coagulation Analyzer

We were tasked with developing a solution to a problem that exists in the biotechnology industry. Patients who undergo blood drawing, centrifugation, and analysis require precise and accurate results. Under the influence of centrifugal force, the blood sample often exhibits a foaming effect when oxygen is introduced, resulting in some layers of the sample becoming foamy. A blood analyzer that uses microfluidics to transfer the sample can struggle with distinguishing the layer of foam from the correct layer of plasma. This presented the problem we were tasked with solving: how do we design a system for a blood analyzer that can distinguish a foam layer from a plasma sample?
