I was looking forward to this...
Ffor almost a second until I realised the display will just be filled with ads.
Researchers have created a new flexible nanomaterial film that boasts a “world record” combination of transparency and electrical conductivity, making it an ideal candidate for roll-up touchscreens. Transparent nanomaterial films have been used for bendable screens before. Lenovo showcased its CPlus, a flexible phone that can …
Since I don't want to pay $9 to rent the article for 48 hours, I'm going to guess that they applied the film to someone's hand and that the red color you're seeing is the actual sheet itself. From the abstract, the sheet resistance is 0.42 ohms/square, which would roughly equate to a corner-to-corner resistance of 1 ohm. In the lower right-hand picture, you can see a little light off to the side with the electrodes applied (and presumably carrying the current to drive it), which appears to show that the patch is indeed conductive.
" I'm going to guess that they applied the film to someone's hand and that the red color you're seeing is the actual sheet itself. "
Your guess is consistent with the relevant figure caption in the article "Images of CuEW-TCEs (duration of the first electrospinning stage t1st = 30 s) transferred to a human hand and ..."
