This paper presents a cost-effective and scalable method for real-time detection of microdroplets in microchannels. Sensing electrodes are manufactured using standard microfabrication techniques. Commercial capacitive sensors are used for detection. The functional and simple hardware ensures portability and yields a signal-to-noise ratio of 4 for electrodes covered with a passivation layer. Experimental results for detection of aqueous droplets in silicone oil are presented.
