Get rid of the cracks! Daniel Reitberg, a tech writer, looks into the future of smart houses that can fix themselves. Think about a world where your walls fix themselves when the vacuum hits them or your coffee table heals itself when it gets scratched. Thanks to the progress in making materials that can fix themselves, this sci-fi idea might be closer than you think. Scientists are putting healing substances inside tiny pills and adding them to these new materials. When there is damage, the capsules pop open, letting the agents that fix the material out. This technology could change the way we live if it is built into smart houses. Think about a time in the future when small scratches and dents don’t happen anymore. Walls automatically fix tiny cracks, furniture recovers from scratches, and floors fix small holes without any trouble. This not only cuts down on costs and upkeep, but it also makes living feel more self-sufficient. But this technology is still very new. More work needs to be done to make self-repairing materials last longer and work better. The present uses may only be able to fix small damage to the surface. Even with these problems, materials that can fix themselves give us a glimpse of a future where our homes are smarter, more responsive, and even self-healing. This would make our homes more like living environments that can change and fix themselves, keeping our homes looking their best for longer.
