Along with providing information concerning stomach contents, stomach simulators enable experts to evaluate the digestion process of foods and drugs. Traditionally, open-loop control approaches were implemented on stomach simulators to produce ACWs. Constructing a closed-loop control system is essential to improve the simulator's ability to imitate ACWs in additional scenarios and avoid constant tuning. Closed-loop control can enhance stomach simulators in accuracy, responding to various food and drug contents, timing, and unknown disturbances. In this article, a new generation of anatomically realistic soft pneumatic gastric simulators is designed and fabricated. The presented simulator represents the antrum, the lower portion of the stomach where ACWs occur. It is equipped with a real-time feedback system to implement diverse closed-loop controllers on demand. All the details of the physical design, fabrication, and assembly process are discussed. Also, the measures taken for the mechatronics design and sensory system are highlighted in this article. Through several implementation algorithms and techniques, three closed-loop controllers, including model-based and model-free schemes are designed and successfully applied on the presented simulator to imitate ACWs. All the experimental outcomes are carefully analyzed and compared against the biological counterparts. It is demonstrated that the presented simulator can serve as a reliable tool and method to scrutinize digestion and promote novel technologies around the human stomach and the digestion process. This research methodology can also be utilized to develop other biomimetic and bioinspired applications.\n                  <\/jats:p>","DOI":"10.1089\/soro.2023.0097","type":"journal-article","created":{"date-parts":[[2024,1,22]],"date-time":"2024-01-22T14:24:51Z","timestamp":1705933491000},"page":"684-697","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":4,"title":["Biomimetic Closed-Loop Control of a Novel Soft Gastric Simulator Toward Emulating Antral Contraction Waves"],"prefix":"10.1177","volume":"11","author":[{"given":"Shahab","family":"Kazemi","sequence":"first","affiliation":[{"name":"Department of Mechanical and Mechatronics Engineering, The University of Auckland, Auckland, New Zealand."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ryman","family":"Hashem","sequence":"additional","affiliation":[{"name":"Department of Medical Physics and Bioengineering, University College London, London, England."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Martin","family":"Stommel","sequence":"additional","affiliation":[{"name":"Department of Electrical and Electronic Engineering, Auckland University of Technology, Auckland, New Zealand."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Leo K.","family":"Cheng","sequence":"additional","affiliation":[{"name":"Auckland Bioengineering Institute, The University of Auckland, Auckland, New Zealand."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Weiliang","family":"Xu","sequence":"additional","affiliation":[{"name":"Department of Mechanical and Mechatronics Engineering, The University of Auckland, Auckland, New Zealand."}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2024,8,21]]},"reference":[{"key":"e_1_3_3_2_2","doi-asserted-by":"publisher","DOI":"10.1109\/TMECH.2017.2748606"},{"key":"e_1_3_3_3_2","doi-asserted-by":"publisher","DOI":"10.1002\/adma.201304018"},{"key":"e_1_3_3_4_2","doi-asserted-by":"publisher","DOI":"10.1039\/C4RA01497A"},{"key":"e_1_3_3_5_2","doi-asserted-by":"publisher","DOI":"10.1111\/aor.12956"},{"key":"e_1_3_3_6_2","doi-asserted-by":"publisher","DOI":"10.1021\/acsabm.8b00753"},{"key":"e_1_3_3_7_2","doi-asserted-by":"publisher","DOI":"10.1109\/TMECH.2013.2276406"},{"key":"e_1_3_3_8_2","doi-asserted-by":"publisher","DOI":"10.3390\/machines10111057"},{"key":"e_1_3_3_9_2","doi-asserted-by":"publisher","DOI":"10.1109\/TMECH.2016.2612262"},{"key":"e_1_3_3_10_2","doi-asserted-by":"crossref","unstructured":"Esser F Steger T Bach D et al.
