Herein, a novel silent speech decoding system is proposed, which employs a self-powered, low-cost, and conformable triboelectric-based E\u2011skin patch and a well-trained multi-layer\u00a0convolutional neural network (CNN)  model. We systematically characterize the structural principles and electrical performance of the E-skin patch. A comparative analysis of labial kinematics during vocalized and silent speech is also conducted, which demonstrates strong consistency in time\u2013frequency domain characteristics. The utilized CNN model is trained across 15 lexical categories (200 samples per category), achieving a high accuracy of 98.75% and demonstrating excellent recognition performance. Furthermore, by integrating human\u2013machine interaction (HMI) and virtual reality (VR) technologies, we develop three representative applications, including a\u00a0real-time lip language visualization system, an\u00a0orofacial-controlled \u201cFeeding Frenzy\u201d interactive game, and a\u00a0VR communication platform with avatar dialogue. This technology enables barrier-free communication for voiceless populations, demonstrating significant potential in HMI, augmentative communication systems, virtual reality integration, and biomedical rehabilitation.<\/jats:p>","DOI":"10.1007\/s40820-026-02346-x","type":"journal-article","created":{"date-parts":[[2026,10,19]],"date-time":"2026-10-19T00:02:04Z","timestamp":1792368124000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Triboelectric E-Skin Patch Decoding Silent Speech for Advanced Human\u2013Machine Interaction and Augmented Virtual Communication"],"prefix":"10.1007","volume":"19","author":[{"given":"Ziwei","family":"Huo","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nuo","family":"Xu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yixuan","family":"Fu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rui","family":"Gu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chao","family":"Liu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhong Lin","family":"Wang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Qijun","family":"Sun","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2026,10,19]]},"reference":[{"issue":"15","key":"2346_CR1","doi-asserted-by":"publisher","first-page":"2101020","DOI":"10.1002\/advs.202101020","volume":"8","author":"H Zhou","year":"2021","unstructured":"H.
