Flexible　electronic　devices　are　attracting　much　attention　on　account　of　their　great　potential　in　artificial　intelligence,　electronic　skin,　and　biomedicine.　However,　the　poor　stretchability,　conductivity,　and　machinability　of　flexible　materials　limit　the　application　of　flexible　electronic　devices　in　practical　environments.　Herein,　hydrogels　with　excellent　mechanical,　electrical,　and　processable　properties　are　synthesized　by　introducing　deep　eutectic　solvent　(DES)　and　MXene　into　a　polyvinyl　alcohol　(PVA)　matrix,　which　shows　more　than　2700%　tensile　strain,　and　1.21 S m−1　conductivity.　Interestingly,　hydrogels　also　exhibited　3D　printable　properties,　enabling　the　fabrication　of　sensors　with　complex　structures　in　a　short　period　of　time.　Besides,　the　serpentine　lines　strain　sensor　is　successfully　prepared　by　digital　light　processing　(DLP)　3D　printing　and　assembled　into　a　bidirectional　strain　rosette　sensor　and　omnidirectional　strain　rosette　sensor,　which　could　recognize　the　direction　and　magnitude　of　stress.　More　importantly,　the　omnidirectional　strain　sensor　can　accurately　distinguish　the　signal　responses　of　different　directions　and　sizes　generated　by　ping-pong　players　swinging　the　racket,　showing　excellent　strain　recognition　ability.　In　brief,　the　hydrogels　designed　are　expected　to　realize　the　manufacture　of　large-scale　and　low-cost　flexible　sensors　through　a　simple　preparation　process,　which　provides　a　new　idea　for　the　manufacture　of　flexible　electronic　devices.　©　2023　Wiley-VCH　GmbH.
