Their broader adoption remains limited by conductive threads that rarely support computerized embroidery (CEmb), reliable electronic integration, and reduced electrochemical capabilities due to coatings that degrade under bending, friction, or aqueous exposure. In this work, we use a dual\u2010thread strategy that integrates silver\u2010plated polyamide threads (AgPT) for high\u2010conductivity pathways with PECOTEX, a chemically resilient PEDOT:PSS\u2010coated cotton thread optimized for biochemical sensing. This approach preserves compatibility with CEmb, enhances electrochemical performance, and reduces cost by reserving AgPT for critical traces. We demonstrate a CEmb\u2010compatible fabrication process for two wearable devices: a fully embroidered SmartBra for electrocardiography and a two\u2010electrode ion sensor for potassium and sodium detection. We validate the design of our wearable dual\u2010thread biosensors through laboratory characterization experiments and evaluate electrochemical sensing performance using a breast milk substitute, enabling realistic testing within women's health and infant\u2010nutrition contexts. By focusing on scalable fabrication and meaningful applications, this work advances embroidered electronic textile systems toward practical, personalized healthcare monitoring.<\/jats:p>","DOI":"10.1002\/smll.75624","type":"journal-article","created":{"date-parts":[[2026,9,10]],"date-time":"2026-09-10T06:51:58Z","timestamp":1789023118000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Bioelectronic Wearable Sensors Produced by Computerized Embroidery Using a Dual Thread Approach"],"prefix":"10.1002","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-1443-2117","authenticated-orcid":false,"given":"Taliya","family":"Weinstein","sequence":"first","affiliation":[{"name":"Department of Bioengineering Royal School of Mines Imperial College London  London UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0009-1941-1700","authenticated-orcid":false,"given":"Xintong","family":"Li","sequence":"additional","affiliation":[{"name":"Department of Bioengineering Royal School of Mines Imperial College London  London UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1677-644X","authenticated-orcid":false,"given":"Hasan","family":"Kurt","sequence":"additional","affiliation":[{"name":"Department of Bioengineering Royal School of Mines Imperial College London  London UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8533-0169","authenticated-orcid":false,"given":"Selin","family":"Olenik","sequence":"additional","affiliation":[{"name":"Department of Bioengineering Royal School of Mines Imperial College London  London UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alexander Silva\u2010Pinto","family":"Collins","sequence":"additional","affiliation":[{"name":"Department of Bioengineering Royal School of Mines Imperial College London  London UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0437-4435","authenticated-orcid":false,"given":"Jos\u00e9 Manuel Rodrigueiro","family":"Flauzino","sequence":"additional","affiliation":[{"name":"Department of Bioengineering Royal School of Mines Imperial College London  London UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Muhammed","family":"Adeel","sequence":"additional","affiliation":[{"name":"Department of Bioengineering Royal School of Mines Imperial College London  London UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1372-7965","authenticated-orcid":false,"given":"Laura","family":"Gonzalez\u2010Macia","sequence":"additional","affiliation":[{"name":"Department of Bioengineering Royal School of Mines Imperial College London  London UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Meral","family":"Y\u00fcce","sequence":"additional","affiliation":[{"name":"Department of Bioengineering Royal School of Mines Imperial College London  London UK"},{"name":"SUNUM Nanotechnology Research and Application Center Sabanci University  Istanbul T\u00fcrkiye"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Firat","family":"G\u00fcder","sequence":"additional","affiliation":[{"name":"Department of Bioengineering Royal School of Mines Imperial College London  London UK"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2026,9,9]]},"reference":[{"key":"e_1_2_9_2_1","doi-asserted-by":"publisher","DOI":"10.1021\/acsnano.2c12606"},{"key":"e_1_2_9_3_1","doi-asserted-by":"publisher","DOI":"10.1109\/MPRV.2021.3078107"},{"key":"e_1_2_9_4_1","first-page":"1","article-title":"E\u2010textiles: A Revolutionary Technology","volume":"1","author":"Ahmad M.
