It's very amazing how far technologies have come today, I've never heard of such a thing. But recently I also heard that many are inventing technologies related to bracelets such as bond touch bracelets, which are designed for long distance relationships. Long-distance relationships can be extremely difficult to handle, and these bracelets are made this way, when you touch this bracelet your partner feels a little vibration and also see an LED light. Isn't that amazing?
