Digital microfluidics: Droplet based logic gates
نویسندگان
چکیده
The authors present microfluidic logic gates based on two-phase flows at low Reynold’s number. The presence and the absence of a dispersed phase liquid slug in a continuous phase liquid represent 1 and 0, respectively. The working principle of these devices is based on the change in hydrodynamic resistance for a channel containing droplets. Logical operations including AND, OR, and NOT are demonstrated, and may pave the way for microfludic system automation and computation. © 2007 American Institute of Physics. DOI: 10.1063/1.2435607

A Design Methodology for Reliable MRF-Based Logic Gates
Probabilistic-based methods have been used for designing noise tolerant circuits recently. In these methods, however, there is not any reliability mechanism that is essential for nanometer digital VLSI circuits. In this paper, we propose a novel method for designing reliable probabilistic-based logic gates. The advantage of the proposed method in comparison with previous probabilistic-based met...
متن کاملA Minimal-Cost Inherent-Feedback Approach for Low-Power MRF-Based Logic Gates
The Markov random field (MRF) theory has been accepted as a highly effective framework for designing noise-tolerant nanometer digital VLSI circuits. In MRF-based design, proper feedback lines are used to control noise and keep the circuits in their valid states. However, this methodology has encountered two major problems that have limited the application of highly noise immune MRF-based circui...
متن کاملEfficient Delay Characterization Method to Obtain the Output Waveform of Logic Gates Considering Glitches
Accurate delay calculation of circuit gates is very important in timing analysis of digital circuits. Waveform shapes on the input ports of logic gates should be considered, in the characterization phase of delay calculation, to obtain accurate gate delay values. Glitches and their temporal effect on circuit gate delays should be taken into account for this purpose. However, the explosive numbe...

We introduce a droplet-jumping phenomenon on a superhydrophobic surface driven by the resonant AC electrowetting. The resonant electrical actuation enables a droplet to accumulate sufficient surface energy for jumping, and superhydrophobic surface minimizes adhesion and hysteresis effects. They provide the effective energy conversion from the surface energy to the kinetic energy and improve the...
متن کاملMicrofluidic logic gates and timers.
We use surface tension-based passive pumping and fluidic resistance to create a number of microfluidic analogs to electronic circuit components. Three classes of components are demonstrated: (1) OR/AND, NOR/NAND, and XNOR digital microfluidic logic gates; (2) programmable, autonomous timers; and (3) slow, perfusive flow rheostats. The components can be implemented with standard pipettes and pro...
