Spray On Antenna System
Just spray it on and it self assembles into an antenna.
I was guessing that it used some kind of conductive block copolymer. A strip of it oscillates when connected to an ohm meter.
I suggested that they use RF coupling strength feedback to adjust the structures while they are still plastic. Perhaps an improved antenna could result if the physical structure could be modified while operating as a proto-antenna. They are going to give it a try.
