LCEs have demonstrated their potential applications in soft robots, soft actuators, artificial muscles, etc. How to align the mesogen orientation and achieve actuations of LCEs are the two most important issues for the studies on LCEs. At present, varied alignment methods and versatile actuations for LCEs have developed rapidly. However, few reviews are addressing these two important issues simultaneously. In this review, three types of alignment methods for LCEs as mechanical stress\u2010induced alignment, external field\u2010induced alignment, and surface effect\u2010induced alignment are summarized, and comparing their programmability toward the mesogen orientation is focused on. The key factors influencing the versatile actuations of LCEs are their orientation structure (intrinsic factor) and the applied external stimuli (extrinsic factor). Thus, actuations are classified into two types on the basis of programmable orientation structure and selective external stimuli, respectively, and focus on comparing their deformation controllability. Finally, an outlook for the future key technologies to develop versatile, precise, and fast\u2010responsive deformation actuations for LCEs is proposed.<\/jats:p><\/jats:sec>","DOI":"10.1002\/aisy.202100065","type":"journal-article","created":{"date-parts":[[2021,11,8]],"date-time":"2021-11-08T00:15:16Z","timestamp":1636330516000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":67,"title":["Varied Alignment Methods and Versatile Actuations for Liquid Crystal Elastomers: A Review"],"prefix":"10.1002","volume":"4","author":[{"given":"Jiayou","family":"Zhao","sequence":"first","affiliation":[{"name":"State Key Laboratory for Strength and Vibration of Mechanical Structures, School of Aerospace Engineering Xi'an Jiaotong University  Xi'an 710049 China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Limei","family":"Zhang","sequence":"additional","affiliation":[{"name":"State Key Laboratory for Strength and Vibration of Mechanical Structures, School of Aerospace Engineering Xi'an Jiaotong University  Xi'an 710049 China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4739-0520","authenticated-orcid":false,"given":"Jian","family":"Hu","sequence":"additional","affiliation":[{"name":"State Key Laboratory for Strength and Vibration of Mechanical Structures, School of Aerospace Engineering Xi'an Jiaotong University  Xi'an 710049 China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2021,11,7]]},"reference":[{"key":"e_1_2_7_2_1","doi-asserted-by":"publisher","DOI":"10.1126\/scirobotics.aax7044"},{"key":"e_1_2_7_3_1","doi-asserted-by":"publisher","DOI":"10.1002\/anie.201915694"},{"key":"e_1_2_7_4_1","doi-asserted-by":"publisher","DOI":"10.1002\/adma.201602745"},{"key":"e_1_2_7_5_1","doi-asserted-by":"publisher","DOI":"10.1002\/adma.201606467"},{"key":"e_1_2_7_6_1","doi-asserted-by":"publisher","DOI":"10.1002\/adma.201701814"},{"key":"e_1_2_7_7_1","doi-asserted-by":"publisher","DOI":"10.1002\/adma.201904224"},{"key":"e_1_2_7_8_1","doi-asserted-by":"publisher","DOI":"10.1038\/35068522"},{"key":"e_1_2_7_9_1","doi-asserted-by":"publisher","DOI":"10.1126\/sciadv.aax5746"},{"key":"e_1_2_7_10_1","doi-asserted-by":"publisher","DOI":"10.1002\/adma.201903452"},{"key":"e_1_2_7_11_1","doi-asserted-by":"publisher","DOI":"10.1039\/B813120C"},{"key":"e_1_2_7_12_1","unstructured":"M.Winkler A.Kaiser S.Krause H.Finkelmann A.
