It　is　an　inevitable　requirement　for　stretchable　triboelectric　nanogenerators　to　be　able　to　sense　external　mechanical　forces　and　convert　them　into　observable　electrical　signals　under　adverse　conditions　(twisting,　stretching,　etc.).　However,　the　vast　majority　of　existing　stretchable　triboelectric　nanogenerators　have　an　inherent　limitation　that　they　cannot　obtain　stable　contact　triboelectric　response　under　stretching　deformation.　Here,　we　propose　a　highly　stretchable　dual-mode　triboelectric　nanogenerator　(SDTENG)　with　both　stretch-insensitive　sensing　and　stretch-sensitive　sensing　properties.　By　the　regional　modulus　modulation　based　on　cross-linked　interpenetrating　network　(IPN),　our　SDTENG　shows　almost　the　same　pressure　sensing　property　represented　by　the　triboelectric　output　in　the　120%　stretch　range,　mainly　because　the　effective　contact　region　of　the　friction　layer　is　high　modulus　and　stretch-unperturbed.　While　in　the　low　modulus　region,　the　MXene/CNT　electrode　of　SDTENG　exhibits　excellent　strain　sensitivity　with　the　stretching　of　the　device,　and　the　gauge　factor　is　up　to　238.8.　The　combination　of　stretch-insensitive　pressure　sensing　and　stretch-sensitive　strain　sensing　makes　our　SDTENG　with　promising　potential　applications　in　wearable　devices　and　smart　robots.
