This is Soramatex from Sora Materials, out of Nagoya University in Japan. It uses carbon powder, which makes it sound like maybe it’s a graphene aerogel — which, to be clear, is a thing that already exists and can get even lighter than this

It provides the most accurate tactile feedback in 3D — as if you were actually touching the object with it. Inverse3 can be used for game development and modeling, as well as remote robot control and even surgeon training — with movement accuracy down to 0.01 mm. It costs $10,000
