However, most proposed solutions evolve towards a target geometry without considering time-dependent actuation paths. To achieve more complex geometries and avoid self-collisions, it is critical to encode a spatial and temporal shape evolution within the initially flat shell. Recent realizations of time-dependent morphing are limited to the actuation of few, discrete hinges and cannot form doubly curved surfaces. Here, we demonstrate a method for encoding temporal shape evolution in architected shells that assume complex shapes and doubly curved geometries. The shells are non-periodic tessellations of pre-stressed contractile unit cells that soften in water at rates prescribed locally by mesostructure geometry. The ensuing midplane contraction is coupled to the formation of encoded curvatures. We propose an inverse design tool based on a data-driven model for unit cells’ temporal responses."}],"volume":11,"file_date_updated":"2020-07-14T12:47:55Z","user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","isi":1,"article_processing_charge":"No","day":"13","publisher":"Springer Nature","department":[{"_id":"BeBi"}],"file":[{"file_size":1315270,"relation":"main_file","file_name":"2020_NatureComm_Guseinov.pdf","file_id":"7336","creator":"rguseino","content_type":"application/pdf","date_updated":"2020-07-14T12:47:55Z","date_created":"2020-01-15T14:35:34Z","access_level":"open_access","checksum":"7db23fef2f4cda712f17f1004116ddff"}],"type":"journal_article","has_accepted_license":"1","article_type":"original","doi":"10.1038/s41467-019-14015-2","article_number":"237","ddc":["000"],"license":"https://creativecommons.org/licenses/by/4.0/","external_id":{"isi":["000511916800015"]},"status":"public","author":[{"full_name":"Guseinov, Ruslan","id":"3AB45EE2-F248-11E8-B48F-1D18A9856A87","first_name":"Ruslan","orcid":"0000-0001-9819-5077","last_name":"Guseinov"},{"first_name":"Connor","last_name":"McMahan","full_name":"McMahan, Connor"},{"id":"2DC83906-F248-11E8-B48F-1D18A9856A87","full_name":"Perez Rodriguez, Jesus","last_name":"Perez Rodriguez","first_name":"Jesus"},{"full_name":"Daraio, Chiara","first_name":"Chiara","last_name":"Daraio"},{"first_name":"Bernd","orcid":"0000-0001-6511-9385","last_name":"Bickel","full_name":"Bickel, Bernd","id":"49876194-F248-11E8-B48F-1D18A9856A87"}],"oa_version":"Published Version","date_updated":"2024-02-21T12:45:02Z","month":"01","ec_funded":1,"year":"2020","publication_identifier":{"issn":["2041-1723"]},"keyword":["Design","Synthesis and processing","Mechanical engineering","Polymers"],"title":"Programming temporal morphing of self-actuated shells","related_material":{"link":[{"url":"https://ist.ac.at/en/news/geometry-meets-time/","description":"News on IST Homepage","relation":"press_release"}],"record":[{"relation":"dissertation_contains","status":"public","id":"8366"},{"id":"7154","relation":"research_data","status":"public"}]},"quality_controlled":"1","project":[{"call_identifier":"H2020","name":"ISTplus - Postdoctoral Fellowships","_id":"260C2330-B435-11E9-9278-68D0E5697425","grant_number":"754411"},{"call_identifier":"H2020","name":"MATERIALIZABLE: Intelligent fabrication-oriented Computational Design and Modeling","_id":"24F9549A-B435-11E9-9278-68D0E5697425","grant_number":"715767"}],"tmp":{"name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","image":"/images/cc_by.png","short":"CC BY (4.0)","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode"},"intvolume":"        11","date_published":"2020-01-13T00:00:00Z","citation":{"chicago":"Guseinov, Ruslan, Connor McMahan, Jesus Perez Rodriguez, Chiara Daraio, and Bernd Bickel. “Programming Temporal Morphing of Self-Actuated Shells.” <i>Nature Communications</i>.
