Due to incoherent scattering, the apparent color of translucent HPC CLCs is often diminished and nearly invisible against white or colored backgrounds. In this work, a cellulose\u2010based mixture with structural coloration and conductivity was engineered by integrating poly(3,4\u2010ethylenedioxythiophene): poly(styrenesulfonate) (PEDOT: PSS) into HPC. The incorporated conductive dark PEDOT: PSS suppresses the effect of incoherent scattering and reduces background\u2010color interference, enabling background\u2010independent structural color. This approach empowers the structural coloration independent of backgrounds and imparts conductivity to the mixture. Leveraging these intriguing properties, the UV\u2010crosslinked HPC\u2010PEDOT: PSS\u2010PEGDA400 gel possesses exceptional sensitivity with a gauge factor of 15.30, combined with a synchronous mechanochromic response. Significantly, the cellulose\u2010based gel is endowed with not only durable and reversible mechanochromic but also electromechanical responses to stimuli such as stretching and finger\u2010bending. The first feature enables intuitive user\u2010visible interactions and supports advanced inflatable displays, while the second feature facilitates the quantitative assessment of mechanical deformation. This work achieves the dual\u2010modal functionalities in a single gel, offering insights into next\u2010generation structural colored materials for multifunctional electronic skins and dynamic displays.<\/jats:p>","DOI":"10.1002\/smll.76140","type":"journal-article","created":{"date-parts":[[2026,10,6]],"date-time":"2026-10-06T10:15:13Z","timestamp":1791281713000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["A Background\u2010Independent Structural Colored Gel Based on Cellulose\/PEDOT: PSS for Highly Sensitive Dual\u2010Mode Sensing"],"prefix":"10.1002","author":[{"given":"Zhenni","family":"Lu","sequence":"first","affiliation":[{"name":"Sino\u2010Luso Joint Laboratory for Optoelectronics Macao Institute of Materials Science and Engineering (MIMSE) Faculty of Innovation Engineering Macau University of Science and Technology  Taipa Macao China"},{"name":"Macau University of Science and Technology Zhuhai MUST Science and Technology Research Institute  Zhuhai China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Binhong","family":"Yu","sequence":"additional","affiliation":[{"name":"Sino\u2010Luso Joint Laboratory for Optoelectronics Macao Institute of Materials Science and Engineering (MIMSE) Faculty of Innovation Engineering Macau University of Science and Technology  Taipa Macao China"},{"name":"Macau University of Science and Technology Zhuhai MUST Science and Technology Research Institute  Zhuhai China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4724-7508","authenticated-orcid":false,"given":"Zhiyuan","family":"Sun","sequence":"additional","affiliation":[{"name":"Sino\u2010Luso Joint Laboratory for Optoelectronics Macao Institute of Materials Science and Engineering (MIMSE) Faculty of Innovation Engineering Macau University of Science and Technology  Taipa Macao China"},{"name":"Macau University of Science and Technology Zhuhai MUST Science and Technology Research Institute  Zhuhai China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yaming","family":"Liu","sequence":"additional","affiliation":[{"name":"Sino\u2010Luso Joint Laboratory for Optoelectronics Macao Institute of Materials Science and Engineering (MIMSE) Faculty of Innovation Engineering Macau University of Science and Technology  Taipa Macao China"},{"name":"Macau University of Science and Technology Zhuhai MUST Science and Technology Research Institute  Zhuhai China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chengjun","family":"Yu","sequence":"additional","affiliation":[{"name":"Sino\u2010Luso Joint Laboratory for Optoelectronics Macao Institute of Materials Science and Engineering (MIMSE) Faculty of Innovation Engineering Macau University of Science and Technology  Taipa Macao China"},{"name":"Macau University of Science and Technology Zhuhai MUST Science and Technology Research Institute  Zhuhai China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6813-0448","authenticated-orcid":false,"given":"Jianxin","family":"Tang","sequence":"additional","affiliation":[{"name":"Sino\u2010Luso Joint Laboratory for Optoelectronics Macao Institute of Materials Science and Engineering (MIMSE) Faculty of Innovation Engineering Macau University of Science and Technology  Taipa Macao China"},{"name":"Macau University of Science and Technology Zhuhai MUST Science and Technology Research Institute  Zhuhai China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yanqing","family":"Li","sequence":"additional","affiliation":[{"name":"School of Physics East China Normal University  Shanghai China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4761-4793","authenticated-orcid":false,"given":"Sui\u2010Dong","family":"Wang","sequence":"additional","affiliation":[{"name":"Sino\u2010Luso Joint Laboratory for Optoelectronics Macao Institute of Materials Science and Engineering (MIMSE) Faculty of Innovation Engineering Macau University of Science and Technology  Taipa Macao China"},{"name":"Macau University of Science and Technology Zhuhai MUST Science and Technology Research Institute  Zhuhai China"},{"name":"State Key Laboratory of Bioinspired Interfacial Materials Science Institute of Functional Nano &amp;
