However, LCEs have lower force outputs than other soft actuators. This work reports an LCE formulation that achieves a 5\u00d7 increase in actuation force through mechanical intervention. Incorporating low\u2010melting\u2010point alloy Field's metal (FM) particles into the LCE matrix both enhances actuation stress and introduces tunable stiffness. At low FM concentrations (\u226410\u2009vol%), actuation stress increases fivefold due to mechanically enhanced network entropy. At higher concentrations (\u224830\u2009vol%), the composite exhibits variable stiffness, behaving metal\u2010like when below the FM's melting point and softening once the FM melts. These formulations not only enhance actuator performance in terms of stress and strain but also mimic muscle\u2010like rheological behavior, advancing LCEs toward practical artificial muscle applications.<\/jats:p>","DOI":"10.1002\/aisy.202401080","type":"journal-article","created":{"date-parts":[[2025,6,29]],"date-time":"2025-06-29T10:18:39Z","timestamp":1751192319000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Enhanced Actuation Stress in Variable Stiffness Liquid Crystal Elastomers"],"prefix":"10.1002","volume":"7","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-7899-3848","authenticated-orcid":false,"given":"Sophia","family":"Eristoff","sequence":"first","affiliation":[{"name":"Department of Mechanical Engineering and Materials Science Yale University  New Haven 06511 CT USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3151-2538","authenticated-orcid":false,"given":"Lina","family":"Sanchez\u2010Botero","sequence":"additional","affiliation":[{"name":"Department of Mechanical Engineering and Materials Science Yale University  New Haven 06511 CT USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2324-8124","authenticated-orcid":false,"given":"Rebecca","family":"Kramer\u2010Bottiglio","sequence":"additional","affiliation":[{"name":"Department of Mechanical Engineering and Materials Science Yale University  New Haven 06511 CT USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2025,6,22]]},"reference":[{"key":"e_1_2_9_2_1","doi-asserted-by":"publisher","DOI":"10.1038\/s41598-022-14784-9"},{"key":"e_1_2_9_3_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.robot.2017.11.005"},{"key":"e_1_2_9_4_1","doi-asserted-by":"publisher","DOI":"10.1109\/LRA.2018.2874379"},{"key":"e_1_2_9_5_1","doi-asserted-by":"publisher","DOI":"10.1002\/aisy.202100140"},{"key":"e_1_2_9_6_1","doi-asserted-by":"publisher","DOI":"10.1002\/aisy.202000128"},{"key":"e_1_2_9_7_1","doi-asserted-by":"publisher","DOI":"10.1002\/advs.201903391"},{"key":"e_1_2_9_8_1","doi-asserted-by":"publisher","DOI":"10.1126\/scirobotics.abc3721"},{"key":"e_1_2_9_9_1","doi-asserted-by":"publisher","DOI":"10.1002\/adma.201704407"},{"key":"e_1_2_9_10_1","doi-asserted-by":"publisher","DOI":"10.1002\/aisy.202100011"},{"key":"e_1_2_9_11_1","doi-asserted-by":"publisher","DOI":"10.1089\/soro.2018.0136"},{"key":"e_1_2_9_12_1","doi-asserted-by":"publisher","DOI":"10.1038\/nature25443"},{"key":"e_1_2_9_13_1","doi-asserted-by":"publisher","DOI":"10.1126\/scirobotics.adi9754"},{"key":"e_1_2_9_14_1","doi-asserted-by":"publisher","DOI":"10.1177\/1687814020933409"},{"key":"e_1_2_9_15_1","doi-asserted-by":"publisher","DOI":"10.3389\/frobt.2018.00069"},{"key":"e_1_2_9_16_1","doi-asserted-by":"publisher","DOI":"10.1242\/jeb.244721"},{"key":"e_1_2_9_17_1","doi-asserted-by":"publisher","DOI":"10.1051\/jp1:1997209"},{"key":"e_1_2_9_18_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0764-4442(99)80373-5"},{"key":"e_1_2_9_19_1","doi-asserted-by":"publisher","DOI":"10.1209\/0295-5075\/132\/36001"},{"key":"e_1_2_9_20_1","doi-asserted-by":"publisher","DOI":"10.1002\/adfm.202402403"},{"key":"e_1_2_9_21_1","first-page":"127","volume-title":"Rheology: Volume 1: Principles","author":"Onogi S.","year":"1980"},{"key":"e_1_2_9_22_1","doi-asserted-by":"publisher","DOI":"10.1122\/1.549634"},{"key":"e_1_2_9_23_1","doi-asserted-by":"publisher","DOI":"10.1021\/la500454d"},{"key":"e_1_2_9_24_1","doi-asserted-by":"publisher","DOI":"10.1038\/nmat4433"},{"key":"e_1_2_9_25_1","doi-asserted-by":"publisher","DOI":"10.1126\/sciadv.aax5746"},{"key":"e_1_2_9_26_1","doi-asserted-by":"publisher","DOI":"10.1073\/pnas.1911021116"},{"key":"e_1_2_9_27_1","doi-asserted-by":"publisher","DOI":"10.1088\/2399-7532\/ab6d1e"},{"key":"e_1_2_9_28_1","doi-asserted-by":"publisher","DOI":"10.1002\/polb.24287"},{"key":"e_1_2_9_29_1","doi-asserted-by":"publisher","DOI":"10.1002\/adfm.201802809"},{"key":"e_1_2_9_30_1","doi-asserted-by":"publisher","DOI":"10.1080\/21680396.2018.1530155"},{"key":"e_1_2_9_31_1","doi-asserted-by":"publisher","DOI":"10.1039\/C7SM01380A"},{"key":"e_1_2_9_32_1","doi-asserted-by":"publisher","DOI":"10.1021\/jacs.9b06757"},{"key":"e_1_2_9_33_1","doi-asserted-by":"publisher","DOI":"10.1080\/19475411.2022.2133188"},{"key":"e_1_2_9_34_1","doi-asserted-by":"publisher","DOI":"10.1039\/D1SM01356D"},{"key":"e_1_2_9_35_1","doi-asserted-by":"publisher","DOI":"10.1002\/aisy.201900163"},{"key":"e_1_2_9_36_1","doi-asserted-by":"publisher","DOI":"10.1038\/s41565-022-01220-2"},{"key":"e_1_2_9_37_1","doi-asserted-by":"publisher","DOI":"10.1002\/adma.201602580"},{"key":"e_1_2_9_38_1","doi-asserted-by":"publisher","DOI":"10.1002\/adfm.201903368"},{"key":"e_1_2_9_39_1","doi-asserted-by":"crossref","unstructured":"T.
