In July, Samsung announced 2021 foldable phone sales were up 300% from 2020, at more than 10 million phones.

Electrically-conductive inks are one of the long-developing technologies already being utilized in the design and manufacturing of products ranging from smartphones to auto- motive, medical devices (like MRI imaging vests), and prototype space suits. High-per- formance electrically conductive inks can be sorted into a few major categories: solids- based inks incorporating materials such as metal or carbon in some form, particle-free metal complex inks, and conductive polymer inks. Full disclosure: I'm a founding member of NovaCentrix, and our team has developed a range of nanoparticle-metal-based conducting inks going back to the early 2000s. at said, I also see great advancements and opportunities for the other types of inks as well.
