Hydrogels are three-dimensional (3-D) polymer networks that can retain large quantities of water in their swollen states for wide applications in bioengineering and materials sciences. Advanced hydrogel fabrication techniques are in development to meet user-specified requirements with substantial constraints placed on the physical and chemical properties of hydrogel precursors and printed structures. In a recent study, Jikun Wang and co-workers at the State Key Lab for Strength and Vibration of Mechanical Structures, Department of Engineering Mechanics, in China, proposed a new method of patterning liquids with the capacitor edge effect (PLEEC). The results are now published in Science Advances.
