Microfluidic pneumatic logic circuits and digital pneumatic microprocessors for integrated microfluidic systems.
We have developed pneumatic logic circuits and microprocessors built with microfluidic channels and valves in polydimethylsiloxane (PDMS). The pneumatic logic circuits perform various combinational and sequential logic calculations with binary pneumatic signals (atmosphere and vacuum), producing cascadable outputs based on Boolean operations. A complex microprocessor is constructed from combina...
متن کاملMicrofluidic Systems Integrated Microfluidic Systems**
Microfluidic systems use networks of channels thinner than a human hair to manipulate nanoliter volumes of reagents. The goal of microfluidics is challenging: to integrate, on a chip smaller than a credit card, all operations normally performed in a chemical or medical laboratory. Synthesis, purification, analysis, and diagnostics would be performed by such a “lab on a chip” rapidly, economical...
متن کاملManually operatable on-chip bistable pneumatic microstructures for microfluidic manipulations.
Bistable microvalves are of particular interest because of their distinct nature of requiring energy consumption only during the transition between the open and closed states. This characteristic can be highly advantageous in reducing the number of external inputs and the complexity of control circuitries since microfluidic devices as contemporary lab-on-a-chip platforms are transferring from r...
متن کاملPneumatic oscillator circuits for timing and control of integrated microfluidics.
Frequency references are fundamental to most digital systems, providing the basis for process synchronization, timing of outputs, and waveform synthesis. Recently, there has been growing interest in digital logic systems that are constructed out of microfluidics rather than electronics, as a possible means toward fully integrated laboratory-on-a-chip systems that do not require any external con...
متن کاملReversible thermo-pneumatic valves on centrifugal microfluidic platforms.
Centrifugal microfluidic systems utilize a conventional spindle motor to automate parallel biochemical assays on a single microfluidic disk. The integration of complex, sequential microfluidic procedures on these platforms relies on robust valving techniques that allow for the precise control and manipulation of fluid flow. The ability of valves to consistently return to their former conditions...
