Artificial　intelligence　is　developing　towards　multimodal　perception,　and　display　technology　is　evolving　into　intelligent　human-computer　interaction.　Owing　to　the　intuitive　and　anti-interference　advantages　of　optical　outputs,　it　is　essential　to　apply　them　to　artificial　multisensory　systems.　Herein,　we　propose　a　multimodal　perception　system　with　optical　feedback　that　utilizes　an　integrated　triboelectric　nanogenerator　(TENG)　in　conjunction　with　a　quantum　dot　light-emitting　synaptic　device　(QLESD),　where　TENG　serves　as　a　receiver　for　pressure　signals　and　QLESD　functions　as　both　ultraviolet　(UV)　light　and　temperature　receptor.　Three　distinct　signals　were　memorized　and　processed　in　QLESD,　which　ultimately　outputs　light　and　electrical　signals　that　combined　these　three　stimuli.　The　excitatory　postsynaptic　current　(EPSC)　and　EP　brightness　(EPSB)　of　QLESD　stimulated　by　pressure　signal　from　TENG　were　systematically　investigated.　Notably,　EPSC　and　EPSB　of　the　QLESD　were　enhanced　with　increasing　contact　frequency.　Furthermore,　as　both　the　temperature　and　UV　light　intensity　increased　gradually,　the　suppression　effect　on　synaptic　signal　transmission　and　memory　became　more　pronounced.　The　successfully　integration　of　temperature　and　UV　light　in　collaborative　modulation　of　pressure　signals　has　been　achieved,　showcasing　remarkable　potential　applications　in　robotics　and　human-computer　interaction.　©　2025　IOP　Publishing　Ltd.　All　rights,　including　for　text　and　data　mining,　AI　training,　and　similar　technologies,　are　reserved.
