Would it be… an invisible touch?
Apparently the material disperses pressure so that you won’t feel anything when you touch it. Like your estranged ex feels.

Researchers at the Karlsruhe Institute of Technology have created a material that sounds like something from a fictional tale: an elasto-mechanical unfeelability cloak. The polymer-based, scaffold-like structure can mask the presence of an object so it’s imperceptible to the human touch.
If you, for example, stepped on a large enough rock, the rubber and foam in your shoe would deform and result in a noticeable bulge. If your shoes were made of the cloaking material, it would disperse the pressure in such a way that you wouldn’t notice the rock beneath your foot.
How Does It Work?
The material consists of precisely calculated needle-shaped elements, such that strength depends on the location in a defined way.
