New Meta-Material Makes Things Invisible To Touch
You won’t feel comfortable lying on such a thin mattress, but imagine if there was such a mattress that was very thin and still able to keep you from feeling whatever was underneath it; won’t you want it? This has been made possible all thanks to Karlsruhe Institute of Technology where a team has managed to come up with a new material that allows for prevention of objects from being felt via touch.
A lot of research has been made on invisibility (because that is fascinating) on the past few years in order to come up with techniques that make us invisible or kill off the sounds we make in order to give us ninja like abilities, but there has been no invention such as the one we are talking about which allows for an object to be not felt when the object is touched. The KIT researchers began with a particular crystalline meta-material which was composed of tiny cones that were joined together at the tips. The measurements are accurate on a sub-micrometer level for the surface to be non-touchable.
Once the material was manufactured, the team placed a hard cylinder within this material. The cylinder could be felt easily through foam, cotton and other soft materials but with the meta-material the cylinder didn’t exist at all. The users didn’t feel anything under the material and this has opened new doors for innovation with this particular type of material.
