Wound or skin treatment devices with variable edge geometries

This invention describes a flexible skin patch, similar to a bandage, designed to help heal wounds or prevent scars. It works by having wavy, non-sharp edges instead of straight ones. When stretched and applied to the skin, these wavy edges help distribute tension more evenly, reducing pressure points that straight edges might create, with the claims specifying the waviness must have a certain amplitude relative to the patch's width.
