Data Rate Performance of Droplet Microfluidic Communication System

2015 
We develop a microfluidic communication system prototype and conduct experiments to show the feasibility of data transmission. We apply using on/off keying and communication by silence modulation schemes for signal transmission. Their performance is evaluated by using data obtained experimentally. The data rate of these modulation schemes is computed as well. We identify the noise sources in microfluidic channels as setup related. The experiments reveal that communication by silence is significantly better than on/off keying. Our results show that both modulation schemes are feasible for signal transmission. Even though CtS outperforms OOK in terms of achievable data rate, from a practical point of view CtS is much harder to control, since there are more parameters to be controlled at the same time.
