Patch comprising sensing components

Abstract

The present invention relates a patch for detecting by at least one non-invasive imaging technique a leak of a biological fluid at an application site, wherein said patch comprises either a layer comprising one or more first portions containing a first gel, one or more second portions containing a second gel and at least one sensing component embedded within the first gel and/or the second gel, or a layer containing a hydrogel and at least one sensing component, such as aerogel particles, and xerogel particles, embedded within said hydrogel.
