It might sound like the stuff of science fiction, but a team of engineers at the California Institute of Technology (Caltech), for the first time ever, has developed just such self-healing integrated chips.
The team demonstrated this self-healing capability in tiny power amplifiers. The amplifiers are so small that 76 of the chips—including everything they need to self-heal—could fit on a single penny.
If this works it will change the world, its the SABRE engine in development by Reaction Engines Ltd. It will use oxygen from the atmosphere as the oxidizer and then switch to on board liquid oxygen reserves to make the final push to space. This right here is the next stepping stone to bringing down the cost of getting people and materials into space.
