Abstract
Digital microfluidics utilises discrete droplets to increase the throughput of chemical and biological assays. There is a great need for sensing techniques that can help automate droplet handing. This work aims to illustrate by means of finite element modelling the factors that affect the measurement of droplet impedance in a thin-walled glass capillary. These include modelling the effect of varying capillary wall thickness, electrode spacing, electrode area, droplet size, shielding and droplet conductivity. The simulation is performed using COMSOL finite element analysis software. The model serves to aid the optimization of the measurement system for application in the measurement of the presence/absence of droplets as well as their chemical and biological content.
