This material can heal itself when cut
Scientists at Carnegie Mellon and the University of Tokyo are showcasing a new composite material with self-healing properties that take cues from lizard tails and starfish arms. MWCNTs-PBS — a composite of polyborosiloxane (PBS) and material multi-walled carbon nanotubes (MWCNTs) — is at the heart (so to speak) of the ‘Self-healing UI.’
When cut in two and places back together, the piece begin to reattach, and the seam disappears, as with the following GIF,
The above heart in one several different scenarios the team has created. In this instance, an on-board sensor is capable of detecting both when it has been cut and when those pieces have been rejoined. It goes to work when it detects the latter. The process isn’t nearly as speedy as the image makes it out to be, however, taking about six hours to fully heal.

Other proposed scenarios include robotic actuators and a “transformative soft controller,” which works thusly,
A single controller detects a finger press motion. Then two controllers were joined to form long touch buttons and worked as a piano keyboard. Next, two connected controllers wrapped around the user’s wrist, working as a wrist band slider device. When three friends came to play a video game, the controller was cut into four pieces and worked as half-sized gaming devices with three touch sensors. After use, the four pieces can be joined into the original two controllers for 6 h.
Other hopeful scenarios include a reusable arm cast that essentially molds itself around the damaged limb and heals itself into place. The team has recently reported its findings and plans to work with scientists in other disciplines to explore potential real world applications for the T-1000-style goo.
