Impedance-based droplet volume and concentration measurement in digital microfluidics
Abstract
In this paper, we report on simplified and improved impedance detection in digital microfluidics for measurement of volume or composition based on electrical properties of the liquids. Compared to other approaches reported in the literature, the platform discussed here simplifies the external circuitry to a single precision resistor and inexpensive DAQ module, while at the same time improving upon detection accuracy and sensitivity. The …
