Fig. 1: Skin adhesive, battery-free intelligent, stretchable, permeable and multi-functional electronics (iSAFE) system for wound management.
From: A skin-interfaced three-dimensional closed-loop sensing and therapeutic electronic wound bandage
a Schematic illustration depicting iSAFE as a multi-functional wound electronic capable of closed-loop sensing and treatment for infected chronic wounds. Highly-integrated configuration endows iSAFE with superior breathability, waterproofness, tissue adhesiveness, anti-bacterial activity, and on-demand therapeutic ability. b Optical images of the iSAFE attached onto the chest. The enlarged image demonstrates the robust adhesion of the iSAFE to skin. c Exploded-view illustration of iSAFE highlighting key layers. d Optical images showing the comparison between conventional wound dressing (left) and our iSAFE (right) for ankle wound treatment. e Optical images of the iSAFE system adhering to wrist and arm and its deformation with skin. f Block diagram of the key components of the iSAFE system. g A radar map comparing the critical performances (i.e., permeability, anti-bacterial ability, skin adhesion, stretchability, waterproofness, sensing, and drug delivery) of our iSAFE against other published systems.
