Scientists at Cornell University (USA) have developed a haptic glove that is partly made of optical fibers. Each finger of this glove thus has a stretchable light guide that combines a transparent polyurethane core and an LED core loaded with absorbing dyes. As soon as the user deforms this light guide by bending a finger or by applying pressure, the dye acts as a developer, making it possible to precisely position the location of the formation / deformation point.
In addition, you need to know more about it.
It would then be “sufficient” to connect this pressure point to a special sensor in order to receive ultra-precise haptic feedback over the entire hand. In short, like a digital second skin. Ultimately, this technology could be adapted to VR / AR or to robots (robotic or humanoid arms). All that remains is to go beyond the prototype phase.
