Integrating　high　ionic　conductivity　and　robust　mechanical　properties　into　one　hydrogel　remains　challenging to date.　In　this　paper,　poly(vinyl　alcohol)/carboxymethyl　chitosan/tannic　acid/NaCl/glycerol　(PCTNG)　organohydrogel　was　prepared　by　introducing　tannic　acid　(TA),　NaCl　and　glycerol　(Gly)　into　poly(vinyl　alcohol)/carboxymethyl　chitosan　(PVA/CMCS)　simultaneously.　Owing　to　the　multiple　hydrogen　bonding　complexations,　the　salting-out　effect　and　metal　coordination,　the　PCTNG　organohydrogel　showed　an　attractive　overall　performance　with　high　tensile　strength　(2.02 MPa),　large　elongation　at　break　(570.82%),　superb　ionic　conductivity　(3.05　S/m),　excellent　thermoplasticity　and　thermally　assisted　self-healing　ability.　Moreover,　the　introduction　of　Gly　made　PCTNG　organohydrogel　had　high　anti-freezing　and　anti-dehydration　properties.　The　introduction　of　TA　and　NaCl　endowed　PCTNG　organohydrogel　with　anti-bacterial　properties.　A　flexible　strain　sensor　was　made　based　on　this　organoydrogel　and　this　strain　sensor　could　detect　various　human　activities.　This　study　provided　a　simple　and　promising　strategy　for　manufacturing　ionic　conductive　organohydrogel　for　flexible　wearable　devices.　Graphical　abstract:　[Figure　not　available:　see　fulltext.]　©　2022,　The　Author(s),　under　exclusive　licence　to　Springer　Nature　B.V.
