1. Who invented the bandage is Earle Dickson, He created the bandage because of his wife named Josephine and she got burned by cooking. He also made it for other people because so if they get hurt they can get a bandage so it can feel better.
2. The issue about bandages being sold at markets is that the bandage wouldn't always work so they had to test it a few times and they also improved it a little bit more. The smart bandage solved the problem about the issue is because it protected it from getting bacteria on it.
3. The two bacteria that they tested it on was acrylic acid and also allylamine. Martina picked those two bacteria because those are very effective and it would hurt a lot.
4. Any other uses that they should use for this technology is that they should make it stay on longer if you get it wet or if it would fall off and you have to have a new bandage for the wound.
