Conductive Paper Could Enable Future Flexible Electronics
May 18, 2017 | ACSEstimated reading time: 1 minute

Roll-up computer screens and other flexible electronics are getting closer to reality as scientists improve upon a growing number of components that can bend and stretch. One team now reports in the journal ACS Applied Materials & Interfaces another development that can contribute to this evolution: a low-cost conductive paper that would be easy to manufacture on a large scale.
Current flexible electronic prototypes are commonly built using polymer thin films. But the cost of these films becomes a factor when they are scaled up. To address this issue, scientists have turned to paper, which is renewable, biodegradable and a fraction of the cost of polymer thin films. The downside of paper is that it’s not conductive, and efforts so far to infuse it with this property have been hindered by scalability and expense. Bin Su, Junfei Tian and colleagues wanted to come up with a new approach.
Using a conventional roller process that’s easy to scale up, the researchers coated paper with soft ionic gels to make it conductive. They sandwiched an emissive film between two layers of the ionic gel paper. When they applied a voltage, the device glowed blue, indicating that electricity was being conducted. It also showed electrical durability, withstanding more than 5,000 cycles of bending and unbending with negligible changes in performance and lasting for more than two months. The researchers say their conductive paper, which costs about $1.30 per square meter and could be fabricated at a rate of 30 meters per minute, could become an integral part of future flexible electronics.

Defense Speak Interpreted: The Autonomous Plane Battle—Skyborg Vs. Loyal Wingman
10/07/2025 | Dennis Fritz -- Column: Defense Speak InterpretedI’m awaiting the updates for the U.S. Air Force's Skyborg and Loyal Wingman airborne driverless vehicles. As the hype of self-driving cars has given way to more mundane autonomous activities, so too has the hype of uncrewed planes given way to reality. In cars, the SAE International association classifies degrees of autonomy from 0 to 5, as do some defense aerospace applications of unmanned flight, which have been reduced to practice, while others remain under development.

Global Sourcing Spotlight: Finding the Balance Between Cost and Quality
09/24/2025 | Bob Duke -- Column: Global Sourcing SpotlightIn global sourcing, pursuing lower costs often takes center stage. It’s the shiny lure that gets buyers to cast their lines into unfamiliar waters. But seasoned professionals know that in the long run, sourcing is less about price tags and more about value. The real magic—and margin—lies in finding the balance between cost and quality.
