Self-Healing Electronics

When I first read this article on self-healing circuits (via ExtremeTech) I wasn't sure how useful it would be. When was the last time you cracked a circuit board?

However, the more I think about it, I suspect the type of damage this could repair is the cause of more issues than I would guess. It is probably the sort of thing that you'll never know you need, but would benefit greatly from.

The worst part is that even if it does get used you'll never know that it is working, only when it isn't. How does a product take off if it solves a problem people don't know they have?

ExtremeTech's take:

There’s no word on whether this same technology could one day be used by Terminators to self-heal shotgun blasts to the face
