Although there already are experimental "telehaptic" systems that allow people to send and receive tactile sensations, they tend to be bulky and awkward. A new one is much slimmer and thus more practical, thanks to the use of piezoelectric materials.

While most smartphones now have haptic feedback built into their screens, the whole screen buzzes, limiting the applications of the technology. A new touchscreen film, however, utilizes LEDs to only vibrate in specific areas.
