Inspired by the hierarchical architecture of skin, modulus engineering has been introduced into artificial tactile systems. However, how stress transmission governs internal electric\u2010field distributions\u2010and how the coupling can be exploited for intelligent tactile perception\u2010remain largely unexplored. Here we report a skin\u2010inspired, gradient\u2010modulus electroluminescent pressure display that directly converts mechanical inputs into spatially resolved optical signals. Guided by\n                    <jats:italic>Hertzian<\/jats:italic>\n                    contact theory, we uncover gradient\u2010modulus\u2010induced stress focusing and deformation localization, which in turn redistributes the internal electric field and sensitizes the emissive layer to pressure. This mechano\u2010electro\u2010optical coupling enables intuitive visualization of tactile stimuli. Furthermore, the resulting spatiotemporal luminescence patterns provide rich information for intelligent tactile recognition. Our results establish a general strategy to bridge mechanical perception and optical output, offering a conceptual route toward visualized electronic skin and next\u2010generation human\u2010machine interfaces.\n                  <\/jats:p>","DOI":"10.1002\/adma.74209","type":"journal-article","created":{"date-parts":[[2026,7,22]],"date-time":"2026-07-22T09:10:56Z","timestamp":1784711456000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Skin\u2010Inspired Relative Elastic Contact Coefficient Toward Electroluminescent Tactus"],"prefix":"10.1002","volume":"38","author":[{"given":"Jihan","family":"Qu","sequence":"first","affiliation":[{"name":"College of Chemistry and Materials Science Guangdong Provincial Key Laboratory of Functional Supramolecular Coordination Materials and Applications Su Bingtian Center For Speed Research and Training Jinan University  Guangzhou P.
