Printable Room Temp "tattoo" circuitry

Something interesting to share. By changing the circuit material to include a nanoparticle sintering layer (polyvinyl alcohol paste and calcium carbonate), researchers were able to print circuits and rudimentary sensors onto human skin as room temp. Good news is it works, they're still working on how to make sure a hot shower doesn't take it off. All the materials are recyclable, so maybe it would be a daily or weekly peel and stick replacement for the time being.

My thinking is that with existing micro-dermal anchors to hold the hardware and using this tattoo circuit to provide the sensory data, the future of wearables and implants might come together.
