LME composites consisting of highly deformable materials and low conductive filler ratios offer high stretchability and good strain\u2010tolerant conductance, while not compromising the functionality of their host systems. Despite advances, actively achieving electrical conductivity for LME composites with a low ratio of fillers is challenging, especially in highly deformable elastomers. Herein, a new fabrication strategy that turns nonconductive LME composites with highly deformable elastomers into conductive ones using a small amount of magnetic Ni\u2010doped LM is introduced. By actively manipulating conductive fillers with an external magnetic field, electrically conductive traces can sustainably be achieved at any desired location. Experimental results show that conductive traces have high conductivity of 2.55\u2009\u00d7\u200910<jats:sup>5<\/jats:sup>\u2009S\u2009m<jats:sup>\u22121<\/jats:sup>, high stretchability (&gt;450%), good strain\u2010tolerant conductance (<jats:italic>R<\/jats:italic>\/<jats:italic>R<\/jats:italic><jats:sub>0<\/jats:sub>\u2009\u2248\u20091.56 at 250% strain), and especially a tensile modulus as low as 60.1\u2009kPa at a very low loading ratio (9.7% by volume). The noncontacting magnetic fabrication also enables the creation of diverse configurations in 1D, 2D, and 3D, offering a broad range of potential applications from robotics, stretchable electronics, wearable devices, smart garments to biomedical systems.<\/jats:p><\/jats:sec>","DOI":"10.1002\/aisy.202200282","type":"journal-article","created":{"date-parts":[[2022,10,26]],"date-time":"2022-10-26T22:49:01Z","timestamp":1666824541000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":20,"title":["Magnetically Engineered Conductivity of Soft Liquid Metal Composites for Robotic, Wearable Electronic, and Medical Applications"],"prefix":"10.1002","volume":"4","author":[{"given":"Trung Thien","family":"Hoang","sequence":"first","affiliation":[{"name":"Graduate School of Biomedical Engineering Faculty of Engineering UNSW  Sydney NSW 2052 Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Phuoc Thien","family":"Phan","sequence":"additional","affiliation":[{"name":"Graduate School of Biomedical Engineering Faculty of Engineering UNSW  Sydney NSW 2052 Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mai Thanh","family":"Thai","sequence":"additional","affiliation":[{"name":"Graduate School of Biomedical Engineering Faculty of Engineering UNSW  Sydney NSW 2052 Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"James","family":"Davies","sequence":"additional","affiliation":[{"name":"Graduate School of Biomedical Engineering Faculty of Engineering UNSW  Sydney NSW 2052 Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Chi Cong","family":"Nguyen","sequence":"additional","affiliation":[{"name":"Graduate School of Biomedical Engineering Faculty of Engineering UNSW  Sydney NSW 2052 Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hoang-Phuong","family":"Phan","sequence":"additional","affiliation":[{"name":"School of Mechanical and Manufacturing Engineering Faculty of Engineering UNSW  Sydney NSW 2052 Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Nigel Hamilton","family":"Lovell","sequence":"additional","affiliation":[{"name":"Graduate School of Biomedical Engineering Faculty of Engineering UNSW  Sydney NSW 2052 Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4980-5251","authenticated-orcid":false,"given":"Thanh Nho","family":"Do","sequence":"additional","affiliation":[{"name":"Graduate School of Biomedical Engineering Faculty of Engineering UNSW  Sydney NSW 2052 Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2022,10,26]]},"reference":[{"key":"e_1_2_8_2_1","doi-asserted-by":"publisher","DOI":"10.1146\/annurev-matsci-080819-125403"},{"key":"e_1_2_8_2_2","doi-asserted-by":"publisher","DOI":"10.1002\/adma.201606425"},{"key":"e_1_2_8_3_1","doi-asserted-by":"publisher","DOI":"10.1073\/pnas.1616377114"},{"key":"e_1_2_8_3_2","doi-asserted-by":"publisher","DOI":"10.1149\/2.0271906jss"},{"key":"e_1_2_8_3_3","doi-asserted-by":"publisher","DOI":"10.1002\/admi.201801857"},{"key":"e_1_2_8_3_4","doi-asserted-by":"publisher","DOI":"10.1039\/C8RA00262B"},{"key":"e_1_2_8_4_1","doi-asserted-by":"publisher","DOI":"10.1002\/adma.201506243"},{"key":"e_1_2_8_5_1","doi-asserted-by":"publisher","DOI":"10.1002\/adma.201405256"},{"key":"e_1_2_8_5_2","doi-asserted-by":"publisher","DOI":"10.1038\/s41563-018-0084-7"},{"key":"e_1_2_8_5_3","doi-asserted-by":"publisher","DOI":"10.1021\/acsami.8b08722"},{"key":"e_1_2_8_5_4","doi-asserted-by":"publisher","DOI":"10.1039\/C9NR03903A"},{"key":"e_1_2_8_5_5","doi-asserted-by":"publisher","DOI":"10.1002\/adma.201404790"},{"key":"e_1_2_8_6_1","doi-asserted-by":"publisher","DOI":"10.1002\/adma.201805536"},{"key":"e_1_2_8_6_2","doi-asserted-by":"publisher","DOI":"10.1002\/admt.202000852"},{"key":"e_1_2_8_6_3","doi-asserted-by":"publisher","DOI":"10.1002\/smll.202005336"},{"key":"e_1_2_8_6_4","doi-asserted-by":"publisher","DOI":"10.1038\/s43246-021-00169-4"},{"key":"e_1_2_8_7_1","doi-asserted-by":"publisher","DOI":"10.1002\/adma.202002929"},{"key":"e_1_2_8_7_2","doi-asserted-by":"publisher","DOI":"10.1126\/sciadv.abg4041"},{"key":"e_1_2_8_7_3","doi-asserted-by":"publisher","DOI":"10.1039\/D0SM00803F"},{"key":"e_1_2_8_8_1","doi-asserted-by":"publisher","DOI":"10.1002\/admt.202000724"},{"key":"e_1_2_8_8_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.sna.2021.112673"},{"key":"e_1_2_8_9_1","doi-asserted-by":"publisher","DOI":"10.1002\/admt.201800435"},{"key":"e_1_2_8_9_2","doi-asserted-by":"publisher","DOI":"10.1109\/ACCESS.2020.3019842"},{"key":"e_1_2_8_9_3","unstructured":"c)L.Sy T.
