In　order　to　resolve　the　instability　of　hydrogel-based　wearable　devices　caused　by　dehydration,　solid-state　flexible　ionogels　were　prepared　from　acrylic　acid　(AAc),　choline　chloride　(ChCl)　and　montmorillonite　(Mt).　The　mechanical　properties　of　the　ionogels　were　measured　by　using　the　universal　testing　machine,　and　the　electrical　conductivity　was　characterized　by　using　the　electrochemical　workstation.　At　the　same　time,　the　electromechanical　responses　under　different　motion　behaviors　were　monitored　by　using　a　digital　multimeter.　Finally,　ionogel　sensors　with　different　complex　structures　were　fabricated　by　using　DLP-3D　printer.　The　results　showed　that　the　synthesized　ionogel　had　high　fracture　strength　(1　-　5.7　MPa),　high　tensile　(fracture　strain　~350%),　and　high　ionic　conductivity　(6.38　-　15.91　mS/m).　Ionogels　demonstrated　excellent　elasticity,　and　as　a　flexible　sensor　it　could　reliably　and　accurately　identify　electromechanical　signals　generated　by　different　strains　and　different　loading　speeds.　The　ionogels　also　showed　good　long-term　stability.　After　being　stored　at　a　high　temperature　of　75　℃　for　100　h,　the　ionogels　still　had　the　same　mechanical　properties,　conductivity　and　electromechanical　response　as　the　original　specimen.　Moreover,　the　porous　structure　of　ionogels　printed　by　using　DLP　showed　a　high　rate　of　separation　and　could　monitor　different　motion　states　of　the　human.　©　2025　Editorial　Board　of　Mechanical　Science　and　Technology　for　Aerospace　Engineering.　All　rights　reserved.
