To address this challenge, dynamics\u2010oriented underwater mechanoreceptor interface (DOUMI), a bioinspired mechanoreception system that realizes simultaneous contact and flow perception using a single receptor, is introduced. This receptor, response\u2010elevated\u2010and\u2010expanded hair\u2010like tactile mechanoreceptor (REEM), is inspired by the mechanoreceptive mechanism of aquatic arthropods. REEM combines structural features from different mechanoreceptive sensilla, enabling it to capture a wide range of stimulus dynamics. Under different stimuli, REEM encodes stimuli dynamics as its oscillations with distinct spectral attributes. Those oscillations are efficiently transferred through mechanical processes and imaging, enabling vision\u2010based extraction and further analysis. Therefore, by evaluating the oscillation dynamics with tailored wavelet\u2010based indices, DOUMI can distinguish between contact\u2010 and flow\u2010induced oscillations at each receptor unit with 90.5% accuracy. Furthermore, DOUMI provides comprehensive 2D mechanoreception with a scalable array of REEMs, delivering capabilities like stimuli spatiotemporal visualization, flow trend detection, and scenario classification with an accuracy of 99.5%. With its robustness and operational efficiency in underwater environments, DOUMI can be easily adapted to existing applications using common materials and hardware, establishing a new, streamlined paradigm for underwater general mechanoreception.<\/jats:p>","DOI":"10.1002\/aisy.202400492","type":"journal-article","created":{"date-parts":[[2024,10,20]],"date-time":"2024-10-20T15:32:32Z","timestamp":1729438352000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Dynamics\u2010Oriented Underwater Mechanoreception Interface for Simultaneous Flow and Contact Perception"],"prefix":"10.1002","volume":"7","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-2293-5168","authenticated-orcid":false,"given":"Hua","family":"Zhong","sequence":"first","affiliation":[{"name":"Department of Computer Science The University of Hong Kong  Central and Western Hong Kong"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yaxi","family":"Wang","sequence":"additional","affiliation":[{"name":"Department of Mechanical Engineering University College London  London WC1E 6BT UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jiahao","family":"Xu","sequence":"additional","affiliation":[{"name":"Department of Mechanical Engineering Southern University of Science and Technology  Shenzhen 518055 China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yu","family":"Cheng","sequence":"additional","affiliation":[{"name":"Department of Mechanical Engineering Southern University of Science and Technology  Shenzhen 518055 China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1872-5283","authenticated-orcid":false,"given":"Sicong","family":"Liu","sequence":"additional","affiliation":[{"name":"Department of Mechanical Engineering Southern University of Science and Technology  Shenzhen 518055 China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jia","family":"Pan","sequence":"additional","affiliation":[{"name":"Department of Computer Science The University of Hong Kong  Central and Western Hong Kong"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Wenping","family":"Wang","sequence":"additional","affiliation":[{"name":"Department of Computer Science &amp; Engineering Texas A&amp;M University  College Station TX 77843\u20103112 USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7726-0770","authenticated-orcid":false,"given":"Zheng","family":"Wang","sequence":"additional","affiliation":[{"name":"Department of Mechanical Engineering Southern University of Science and Technology  Shenzhen 518055 China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2024,10,20]]},"reference":[{"key":"e_1_2_9_2_1","doi-asserted-by":"publisher","DOI":"10.1109\/JSEN.2013.2259227"},{"key":"e_1_2_9_3_1","doi-asserted-by":"publisher","DOI":"10.3390\/applmech2020021"},{"key":"e_1_2_9_4_1","doi-asserted-by":"publisher","DOI":"10.1002\/rob.21538"},{"key":"e_1_2_9_5_1","doi-asserted-by":"crossref","unstructured":"S.Li X.Yin C.Xia L.Ye X.Wang B.Liang inProc. of the 2022 Int.
