With　the　increasing　demand　for　wearable　sensing　devices　equipped　with　hydrogels　for　motion　intent　recognition　and　health　monitoring　applications,　it　is　urgent　to　carry　out　research　on　enhancing　their　comfort　and　breath-ability.　Gel/PVA/DPy　breathable　hydrogels　with　high　breathability,　excellent　electrical　conductivity,　and　sensing　ability　were　prepared　by　the　fermentation　method　using　gelatin　and　polyvinyl　alcohol　to　create　a　dual-network　structure　of　hydrogels　with　Dopamine-modified　polypyrrole(DPy)　serving　as　a　conductive　filler.　The　prepared　hydrogel　film　exhibits　excellent　air　permeability　(5.83　mg　&　sdot;cm-2　&　sdot;h-1),　tensile　sensitivity　(GF=5.14),　compressive　sensitivity　(GF　=　5.33),　outstanding　responsiveness　to　external　tensile　stimulation　(response　time　of　0.30　s,　recovery　time　of　0.20　s),　and　exceptional　responsiveness　to　external　compressive　stimuli　(response　time　of　0.20　s,　recovery　time　of　0.30　s).　The　film　is　utilized　as　a　high-sensitivity,　high-precision　wearable　sensor　for　monitoring　activities　such　as　finger　bending,　facial　micro-expressions,　wrist　swinging,　and　throat　vocalizations;　for　real-time　pressure-sensitive　arrays;　and　for　controlling　electronic　devices　for　gaming.　This　study　offers　a　design　concept　and　reference　for　preparing　breathable　hydrogel　films　for　wearable　sensors.
