We report an elastomer-based electrostatic microvalve that was fabricated using replica molding, micro-transfer printing, and plasma bonding. The microvalve can be actuated with an electric potential of ∼220 V and can withstand pressures up to 3 kPa. Sixteen independentlyoperated valves were integrated on a single chip and operated with portable electronics.[2013-0101]
Additive manufacturing (AM, 3D Printing) of hierarchical polymer structures for a targeted function represents a grand challenge in the field of polymer science and engineering. Because advanced functional materials often do not possess suitable mechanical and rheological properties for conventional fused deposition modeling, a key challenge that researchers face is in integrating custom deposition tool heads that enable printing of non-filamentary materials while preserving synchrony with the motion axes. In this article, we demonstrate a highly versatile hardware and software platform for melt and solutionphase benchtop AM and highlight patterning and post-deposition processing of
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
