Electrical Textile Valves for Paper Microfluidics
Advanced Materials, 2017 This paper describes electrically‐activated fluidic valves that operate based on electrowetting through textiles. The valves are fabricated from electrically conductive, insulated, hydrophobic textiles, but the concept can be extended to other porous materials. When the valve is closed, the liquid cannot pass through the hydrophobic textile.

Tunable-Delay Shunts for Paper Microfluidic Devices [PDF]
Analytical Chemistry, 2013 We demonstrate a novel method for controlling fluid flow in paper-based devices. The method delays fluid progress through a porous channel by diverting fluid into an absorbent pad-based shunt placed into contact with the channel. Parameters to control the delay include the length and the thickness of the shunt.
