Wound　management　plays　a　crucial　role　in　nursing　care　as　it　facilitates　effective　wound　healing　and　prevents　infections.　To　overcome　limitations　associated　with　traditional　treatment　methods,　various　smart　bandages　have　been　developed.　The　monitoring　of　wound　parameters　and　the　implementation　of　targeted　treatments　are　crucial　aspects　of　smart　bandage　development.　Smart　bandages,　as　cutting-edge　flexible　wearable　medical　devices,　integrate　various　sensing　technologies,　providing　new　insights　for　dynamic　monitoring　and　personalized　treatment　of　chronic　wounds.　This　paper　systematically　summarizes　the　applications　and　developments　of　smart　bandages　in　monitoring　wound　environmental　parameters,　focusing　on　two　major　detection　methods:　colorimetric　sensing　and　electrochemical　sensing.　Colorimetric　sensors　typically　rely　on　color　changes　induced　by　physiological　parameters,　which　can　not　only　be　identified　by　the　naked　eye　but　also　combined　with　image　recognition　algorithms　for　physiological　parameter　detection.　Electrochemical　sensors,　on　the　other　hand,　modify　electrodes　with　specific　enzymes　and　detect　physiological　parameters　through　the　electrical　signals　generated　by　redox　reactions.　In　addition　to　sensing,　this　paper　further　explores　the　integrated　application　of　three　smart　therapeutic　strategies　in　smart　bandages,　including　promoting　cell　proliferation　and　angiogenesis　through　electrical　stimulation,　achieving　controlled　drug　release　via　responsive　materials,　and　utilizing　photothermal　materials　for　efficient　antibacterial　treatment　of　wounds.　Finally,　the　paper　delves　into　the　challenges　these　bandages　face　in　system　integration　and　clinical　translation,　and　discusses　their　potential　in　personalized　wound　care.　©　2025　Elsevier　B.V.
