abstract = "The design, fabrication, and characterization of a novel microfluidic sensing architecture are presented. The system allows for the position of a fluidic element to be monitored throughout a complex two-dimensional microfluidic network. Sensors consisting of small electrical components (resistors, capacitors, or conduction gaps) are placed within an interconnected fluidic network and are addressed using a multiplexing approach that allows an array of m×n sensors to be supported by only m+n+l electrical contacts. The multiplexing relies on the fact that each sensing element is connected to two electrical leads, and each electrical lead is connected to multiple sensing elements. Herein, the basic principles of electrical resistive sensors are discussed and typical detection traces are presented. Finally, as a proof of the multiplexing concept, a 4×4 array of resistive sensors is used to monitor the passage of a discrete fluid plug through a microfluidic network. copyright The Electrochemical Society.",
