Oh excellent, this is PragmatIC’s work. I first saw this in 2017 when they were still at the centimeter level with 10 layers.
It’s not yet using conventional ink-printing technologies, but this is still promising.
I’m really interested in how many thermal cycles this sort of product can take. It might be ironic if a processor essentially meant to be disposable might survive better than a silicon one.
Seems interesting for wearable electronics.
