To　achieve　smart　and　personalized　medicine,the　development　of　hydrogel　dressings　with　sensing　proper-ties　and　biotherapeutic　properties　that　can　act　as　a　sensor　to　monitor　of　human　health　in　real-time　while　speeding　up　wound　healing　face　great　challenge.In　the　present　study,a　biocompatible　dual-network　composite　hydrogel(DNCGel)sensor　was　obtained　via　a　simple　process.The　dual　network　hydrogel　is　constructed　by　the　interpenetration　of　a　flexible　network　formed　of　poly(vinyl　alcohol)(PVA)physical　cross-linked　by　repeated　freeze-thawing　and　a　rigid　network　of　iron-chelated　xanthan　gum(XG)impreg-nated　with　Fe3+interpenetration.The　pure　PVA/XG　hydrogels　were　chelated　with　ferric　ions　by　immer-sion　to　improve　the　gel　strength(compressive　modulus　and　tensile　modulus　can　reach　up　to　0.62　MPa　and　0.079　MPa,respectively),conductivity(conductivity　values　ranging　from　9　×　10-4　S/cm　to　1　×　10-3　S/cm)and　bacterial　inhibition　properties(up　to　98.56％).Subsequently,the　effects　of　the　ratio　of　PVA　and　XG　and　the　immersion　time　of　Fe3+on　the　hydrogels　were　investigated,and　DNGel3　was　given　the　most　priority　on　a　comprehensive　consideration.It　was　demonstrated　that　the　DNCGel　exhibit　good　biocom-patibility　in　vitro,effectively　facilitate　wound　healing　in　vivo(up　to　97.8％healing　rate)under　electrical　stimulation,and　monitors　human　movement　in　real　time.This　work　provides　a　novel　avenue　to　explore　multifunctional　intelligent　hydrogels　that　hold　great　promise　in　biomedical　fields　such　as　smart　wound　dressings　and　flexible　wearable　sensors.
