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.

Invisibility Scientists Make Visible Improvements in Their Technology

Further improvements in real life cloaking devices are being reported. Disinfo brought you this story earlier in the year and now it looks like the technology has made another huge step forward. TG Daily reports:

Duke University scientists say they’ve succeeded for the first time in building a truly effective invisibility cloak.

When the team first developed a cloaking device back in 2006, one of the biggest problems was the appearance of minor reflections around the edges.

These were similar to the reflections seen when looking through a clear piece of glass, and made the cloaking less than perfect.

Now, though, they say they’ve cracked the problem.

“In order to create the first cloaks, many approximations had to be made in order to fabricate the intricate meta-materials used in the device,” says graduate student Nathan Landy.

“One issue, which we were fully aware of, was loss of the waves due to reflections at the boundaries of the device.”

But he’s now been able to reduce the occurrence of reflections by using a different fabrication strategy.
