New Band-Aid Doesn’t Hurt When You Take it OffMadeline Holler
Band-Aids can fix almost any boo-boo, including the not so apparent ones. But they make it all better only until it’s time to take them off. Removing a Band-Aid can really make things feel worse.
Until now. Biomedical engineers at the Massachusetts Institute of Technology and Brigham and Women’s Hospital in Boston have developed a new kind of bandage — one that sticks on the skin but comes off like a dream.
The new invention was unveiled in the journal Proceedings of the National Academy of Sciences, which describes how the three-layer tape keeps the adhesive layer attached to the bandage. Here’s how it’s described in TIME:
The interface substance is designed to be strong when pulled in almost any direction that a bandage might experience force, but to peel apart easily when the tape is pulled up and off. The inspiration for the idea came from nature,where this property, in which a material is much stronger along one axis than it is along another, is called anisotropy. Just as it’s easier to split a piece of wood along the grain than against it, the new medical tape requires only gentle force to break apart when you peel it, but it still sticks securely when you try to tear at it lengthwise, or when you stretch it out flat.
A little gunk is left behind when you pull off the tape, but it rubs off easily.
Not only is the new tape a boon for kids and wimpy bleeders everywhere, it’s a game changer for hospitals treating the elderly and others with weak skin, which is easily torn by simply pulling on it.
There’s no date yet for when the new bandage will be available in stores, but hopefully some manufacturer will go ahead and just rip off the Band-aid and invest in this new product.
Kids rejoice! Metaphor users, on the other hand, are crushed.
