Electrical Sensing in Segmented Flow Microfluidics

Microfluidic systems require measurement techniques to assess the bioprocesses taking place within these systems. In droplet-based microfluidics, sensing systems have thus far been dominated by the use of optical sensing techniques. Direct electrical measurement of droplets has been quite rare. This chapter describes the use of electrical sensors in droplet-based microfluidics. Electrical sensors offer a possibility to measure the presence/position of droplets but also their electrical properties.
