I choose a Band-Aid. The verification protocol makes sure the inputs matches the outputs. I believe the inputs would be that it sticks to the skin but can be removed without much force and that it doesn’t irritate the skin. A verification test would test for this. I think the verification protocol would call to first test the stickiness on the skin. I would probably ask for volunteers and apply a Band-Aid prototype to there skin and remove it the next day. If the Band-Aid didn’t stick for most volunteers then I would fail it. If it did, then I would pass it. If it was too hard to remove the next day, I would fail it. I would also look for irritation on the skin of volunteers. If my inputs match my outputs then it would pass.
