However, their practical development is constrained by the\u00a0narrow electrochemical stability window (ESW) of AQPEs and the structural instability of electrode\u2013electrolyte interfaces under deformation. Here, we present a \u201cwater\u2010in\u2010network\u201d (WIN) electrolyte that precisely engineers water activity and dynamics by modulating the crosslinking density of the polymer network. We unanticipatedly discover a distinct \u201cwater confinement\u201d effect wherein water activity exhibits a non\u2010monotonic dependence on crosslinking density, originating from the structural evolution of the network. Benefiting from this mechanism, the ESW significantly expands to 3.4\u00a0V, endowing an all\u2010polymer sodium\u2010ion fiber battery with an energy density of 92.4\u00a0Wh kg\n                    <jats:sup>\u22121<\/jats:sup>\n                    . Crucially, in situ interfacial polymerization following electrolyte pre\u2010infiltration forms a mechanically interlocked electrode\u2013electrolyte interface, effectively suppressing water\u2010induced delamination and preserving 78% capacity after 12\u00a0000 bending cycles.When seamlessly woven into a shirt, the fiber batteries can power the fabric\u2010based chemical sensor, enabling real\u2010time, on\u2010body health monitoring across various activities.\n                  <\/jats:p>","DOI":"10.1002\/adma.73599","type":"journal-article","created":{"date-parts":[[2026,6,2]],"date-time":"2026-06-02T08:18:14Z","timestamp":1780388294000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Energetic All\u2010Polymer Fiber Batteries Enabled by Interface\u2010Interlocked Water\u2010In\u2010Network Electrolytes for Wearable Electronics"],"prefix":"10.1002","volume":"38","author":[{"given":"Kangkang","family":"Jia","sequence":"first","affiliation":[{"name":"School of Science Harbin Institute of Technology (Shenzhen)  Shenzhen China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Qimin","family":"Liang","sequence":"additional","affiliation":[{"name":"School of Science Harbin Institute of Technology (Shenzhen)  Shenzhen China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yang","family":"Hong","sequence":"additional","affiliation":[{"name":"Department of Chemistry and Biotechnology School of Engineering The University of Tokyo  Tokyo Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jiahao","family":"Zhu","sequence":"additional","affiliation":[{"name":"School of Science Harbin Institute of Technology (Shenzhen)  Shenzhen China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jinze","family":"Wang","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Silicon and Advanced Semiconductor Materials School of Materials Science and Engineering Zhejiang University  Hangzhou China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xin","family":"Wang","sequence":"additional","affiliation":[{"name":"Department of Mechanical and Energy Engineering SUSTech Energy Institute For Carbon Neutrality Southern University of Science and Technology  Shenzhen China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Weijing","family":"Zuo","sequence":"additional","affiliation":[{"name":"School of Science Harbin Institute of Technology (Shenzhen)  Shenzhen China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jiajun","family":"Tan","sequence":"additional","affiliation":[{"name":"School of Science Harbin Institute of Technology (Shenzhen)  Shenzhen China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Min","family":"Wang","sequence":"additional","affiliation":[{"name":"School of Science Harbin Institute of Technology (Shenzhen)  Shenzhen China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiaohua","family":"Zhong","sequence":"additional","affiliation":[{"name":"Wuhan Tanweng Technology Co.
