Iowa State University engineers have developed a new flexible, stretchable, and  tunable “meta-skin” (metamaterial) “invisibility cloak” that uses rows of small liquid-metal devices to cloak an object from radar over a wide range of frequencies — and possibly at visible or infrared light ranges in the future.

The  skin has rows of split ring resonators embedded inside layers of silicone sheets.
