Sensitivity Optimization of Microfluidic Capacitance Sensor using COMSOL Multiphysics

There is an increasing demand for affordable and accessible healthcare around the world in light of the increasing population. Diagnostics is a major aspect of healthcare, wherein certain measurements on body parameters need to be performed. Recent innovations in miniature chips that are cheap, low power and highly sensitive bring us closer to this goal. These lab on chips have many different components, which can be broadly divided into sample preparation, sample mixing/reaction and output characterization. To retain all the aforementioned benefits it is of utmost importance that all these components or sub systems are on a single chip.
