> The Meta-NFS device concentrates microwave energy into a zone smaller than 200 micrometers, about the width of a human hair, enabling electronics to be printed onto bone, tissue, and living plants

> The Meta-NFS works by heating from within the deposited material itself. A conventional transmission-line microwave applicator

I can't think of any sci-fi plot that anticipated this. Heating a material from within to apply on to sensitive mediums like skin tissue potentially opening applications that go beyond nano-suit imaginations.
