Were you expecting magic?
- yjftsjthsd-h 6y agoI went in expecting some sort of clickbait (since, y'know, paper isn't exactly known for its electrical properties), but I'd assumed that when they said "[w]ith a simple piece of paper" they really meant a piece of paper. I expected it to be "with just a simple piece of paper an a $14k sound analysis / SDR / magnetism detection rig, we can detect force on the paper", which is still clickbait but would've at least struck me as interesting/novel, as opposed to "we layered actual electronics on paper", which could be interesting if they're pioneering flexible electronics or something but makes the paper basically irrelevant.

They created a spray on invisible circuit board that can both detect touch inputs and generate enough electricity to power a bluetooth radio. They achieved all this for a unit cost of 25 cents. That's a pretty amazing achievement and opens up some quite practical uses. Imagine something like Nintendo Labo, but with so many more opportunities for interactivity. Another idea, imagine a student's notebook that synchronized their writing with their phone.
