A Bandage That Talks Back
A regular bandage covers a cut. A smart bandage does that and more. Tiny sensors check the temperature and wetness of the cut.
If the bandage notices the cut is too warm or strange-feeling, it sends a little message to a phone. A grownup or nurse can then take a look.
When it helps most
- After a small surgery
- For burns that take time to heal
- When a kid keeps poking the cut
The big idea: a smart bandage is a tiny helper that tells grownups how a cut is doing without anyone peeking under it.
