Traditional pneumatic suction cups rely on bulky and noisy vacuum sources and need for preloading while electrostatic adhesion\u2010detachment devices generally cannot provide enough adhesion force. To address these shortcomings, a liquid\u2010amplified electrostatically driven suction cup is proposed inspired by octopus's sucker, including a negative pressure chamber with a wrinkle\u2010like membrane and a sealing ring. The negative pressure chamber generates the active adhesion force enhanced by the wrinkle\u2010like membrane, increasing the adhesion strength tenfold compared to pure electrostatic adhesion. The suction cup proposed herein has a remarkable capacity to generate an adhesion force of 56.4 times its weight, without preloading. Additionally, it can adapt to different materials, not only the dry but also the oil\u2010contaminated ones. This presented liquid\u2010amplified electrostatically driven suction cup can offer enhanced adhesion performance for applications in challenging environments.<\/jats:p>","DOI":"10.1002\/aisy.202400279","type":"journal-article","created":{"date-parts":[[2024,6,19]],"date-time":"2024-06-19T12:21:38Z","timestamp":1718799698000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Liquid\u2010Amplified Electrostatically Driven Octopus Sucker\u2010Inspired Suction Cup"],"prefix":"10.1002","volume":"7","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-8646-277X","authenticated-orcid":false,"given":"Yu","family":"Sun","sequence":"first","affiliation":[{"name":"School of Mechanical Engineering Xi'an Jiaotong University  Xi'an 710049 China"}]},{"given":"Lingjun","family":"Tang","sequence":"additional","affiliation":[{"name":"School of Mechanical Engineering Xi'an Jiaotong University  Xi'an 710049 China"}]},{"given":"Ling","family":"Wang","sequence":"additional","affiliation":[{"name":"School of Mechanical Engineering Xi'an Jiaotong University  Xi'an 710049 China"}]},{"given":"Qingkai","family":"Guo","sequence":"additional","affiliation":[{"name":"School of Mechanical Engineering Xi'an Jiaotong University  Xi'an 710049 China"}]},{"given":"Yuxin","family":"Lv","sequence":"additional","affiliation":[{"name":"School of Mechanical Engineering Xi'an Jiaotong University  Xi'an 710049 China"}]},{"given":"Laihao","family":"Yang","sequence":"additional","affiliation":[{"name":"School of Mechanical Engineering Xi'an Jiaotong University  Xi'an 710049 China"}]}],"member":"311","published-online":{"date-parts":[[2024,6,19]]},"reference":[{"key":"e_1_2_8_2_1","doi-asserted-by":"publisher","DOI":"10.1089\/soro.2017.0133"},{"key":"e_1_2_8_3_1","doi-asserted-by":"publisher","DOI":"10.1002\/admt.201800304"},{"key":"e_1_2_8_4_1","doi-asserted-by":"publisher","DOI":"10.1002\/admt.202000676"},{"key":"e_1_2_8_5_1","doi-asserted-by":"publisher","DOI":"10.1088\/1361-665X\/aba848"},{"key":"e_1_2_8_6_1","doi-asserted-by":"publisher","DOI":"10.1021\/acsnano.1c05130"},{"key":"e_1_2_8_7_1","doi-asserted-by":"publisher","DOI":"10.1002\/aisy.202100034"},{"key":"e_1_2_8_8_1","doi-asserted-by":"publisher","DOI":"10.1002\/advs.202100641"},{"key":"e_1_2_8_9_1","doi-asserted-by":"publisher","DOI":"10.1126\/scirobotics.abm6695"},{"key":"e_1_2_8_10_1","doi-asserted-by":"publisher","DOI":"10.1126\/sciadv.abq1905"},{"key":"e_1_2_8_11_1","doi-asserted-by":"publisher","DOI":"10.1109\/LRA.2023.3263377"},{"key":"e_1_2_8_12_1","doi-asserted-by":"publisher","DOI":"10.1098\/rsif.2013.1089"},{"key":"e_1_2_8_13_1","doi-asserted-by":"publisher","DOI":"10.1126\/science.aaf1092"},{"key":"e_1_2_8_14_1","doi-asserted-by":"publisher","DOI":"10.1002\/adma.201504264"},{"key":"e_1_2_8_15_1","doi-asserted-by":"publisher","DOI":"10.1088\/1361-6463\/aa6be4"},{"key":"e_1_2_8_16_1","doi-asserted-by":"publisher","DOI":"10.1126\/scirobotics.aat2874"},{"key":"e_1_2_8_17_1","doi-asserted-by":"publisher","DOI":"10.1126\/scirobotics.aau3038"},{"key":"e_1_2_8_18_1","doi-asserted-by":"publisher","DOI":"10.1089\/soro.2018.0120"},{"key":"e_1_2_8_19_1","doi-asserted-by":"publisher","DOI":"10.1021\/acsami.0c17096"},{"key":"e_1_2_8_20_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.eml.2022.101720"},{"key":"e_1_2_8_21_1","doi-asserted-by":"publisher","DOI":"10.1109\/TRO.2023.3294920"},{"key":"e_1_2_8_22_1","doi-asserted-by":"publisher","DOI":"10.1002\/aisy.202200209"},{"key":"e_1_2_8_23_1","doi-asserted-by":"publisher","DOI":"10.1109\/LRA.2023.3251181"},{"key":"e_1_2_8_24_1","unstructured":"F.Huashan D.Wenhao C.Ningli inA Bionic Micro Sucker Actuated by IPMC Vol. 2014 IEEE Int.
