There have been previously studies on the use of LCEs for reversible changes in surface topography. However, surface protrusions have typically been limited to the order of 1\u2009\u03bcm or depend on light, heat, or electrical stimulation that are difficult to locally control or require relatively high voltage. This article presents a novel operation mode of LCE actuators based on the wrinkling behavior of an LCE\u2010elastomer bilayer architecture. Embedding a liquid\u2010metal\u2010based conductive ink within the LCE enables electrical control of surface wrinkling through Joule heating. The actuator cells can generate wrinkles with amplitudes ranging from 17 to 45\u2009\u03bcm within 30\u2009s under an input power of 2\u2009W and a voltage on the order of 1\u2009V. As the bilayer is composed entirely of soft materials, it is highly deformable, flexible, and can be integrated into a multi\u2010cell array capable of bending on curved surfaces.<\/jats:p><\/jats:sec>","DOI":"10.1002\/aisy.202200402","type":"journal-article","created":{"date-parts":[[2023,4,6]],"date-time":"2023-04-06T05:03:07Z","timestamp":1680757387000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":17,"title":["Electrically Controlled Liquid Crystal Elastomer Surfaces for Dynamic Wrinkling"],"prefix":"10.1002","volume":"6","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-4643-4579","authenticated-orcid":false,"given":"Zefang","family":"Li","sequence":"first","affiliation":[{"name":"Department of Mechanical Engineering Carnegie Mellon University  Pittsburgh PA 15213 USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Gina","family":"Olson","sequence":"additional","affiliation":[{"name":"The Mechanical and Industrial Engineering Department University of Massachusetts  Amherst MA 01003 USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Dinesh K.","family":"Patel","sequence":"additional","affiliation":[{"name":"Human-Computer Interaction Institute Carnegie Mellon University  Pittsburgh PA 15213 USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lining","family":"Yao","sequence":"additional","affiliation":[{"name":"Human-Computer Interaction Institute Carnegie Mellon University  Pittsburgh PA 15213 USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6469-9645","authenticated-orcid":false,"given":"Carmel","family":"Majidi","sequence":"additional","affiliation":[{"name":"Department of Mechanical Engineering Carnegie Mellon University  Pittsburgh PA 15213 USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2023,4,6]]},"reference":[{"key":"e_1_2_9_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/S1369-7021(10)70128-0"},{"key":"e_1_2_9_3_1","first-page":"10","volume-title":"Actuators","author":"Scalet G.","year":"2020"},{"key":"e_1_2_9_4_1","doi-asserted-by":"publisher","DOI":"10.1089\/soro.2016.0008"},{"key":"e_1_2_9_5_1","doi-asserted-by":"publisher","DOI":"10.1126\/sciadv.aao3865"},{"key":"e_1_2_9_6_1","doi-asserted-by":"publisher","DOI":"10.1039\/D1TC00468A"},{"key":"e_1_2_9_7_1","doi-asserted-by":"publisher","DOI":"10.1002\/admt.201900071"},{"key":"e_1_2_9_8_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.apmt.2022.101449"},{"key":"e_1_2_9_9_1","doi-asserted-by":"publisher","DOI":"10.1126\/scirobotics.aau7557"},{"key":"e_1_2_9_10_1","unstructured":"T.Hino T.Maeno inProc. of The Int.
