However, TENGs still face numerous obstacles in terms of sensitivity, long-term stability, and data processing. This paper describes a TENG named DHXN-TENG, which uses a hydrogel named DHXN as its substrate and features a microneedle structure on its upper surface. The DHXN hydrogel exhibits outstanding performance, including high sensitivity (gauge factor (GF): 5.46, strain range: 510%), fast response time (60 ms), fatigue resistance, and good biocompatibility. The DHXN-TENG based on the DHXN hydrogel has an extremely short response time (30 ms), overcoming the limitation of existing self-powered sensors that struggle to acquire signals in real time due to dynamic response hysteresis. At the same time, the DHXN-TENG has a maximum power output of 8.38 W m\u20132 and an extremely high surface charge density, fundamentally eliminating the risk of battery leakage. Furthermore, the DHXN-TENG demonstrates excellent output stability in environments with fluctuating temperature and humidity while also offering reliable long-term durability. In this study, leveraging the exceptional sensing performance of the DHXN-TENG and integrating wireless Bluetooth technology, we developed a wireless remote intelligent monitoring system for foot movement patterns. The system incorporates deep learning algorithms based on convolutional neural networks for gait recognition and rehabilitation assistance. The DHXN-TENG demonstrates significant potential in the fields of medical rehabilitation and human\u2013computer interaction technology.<\/jats:p>","DOI":"10.1021\/acsami.6c13783","type":"journal-article","created":{"date-parts":[[2026,9,24]],"date-time":"2026-09-24T16:02:21Z","timestamp":1790265741000},"page":"53981-53993","source":"Crossref","is-referenced-by-count":0,"title":["AI-Driven Self-Powered Wearable Sensors for Gait Detection"],"prefix":"10.1021","volume":"18","author":[{"given":"Mengfan","family":"Zhang","sequence":"first","affiliation":[{"name":"Northeastern University , , ,","place":["Shenyang, China, 110169"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"He","family":"Liu","sequence":"additional","affiliation":[{"name":"Northeastern University , , ,","place":["Shenyang, China, 110169"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lei","family":"Ouyang","sequence":"additional","affiliation":[{"name":"Northeastern University , , ,","place":["Shenyang, China, 110169"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xinan","family":"Yao","sequence":"additional","affiliation":[{"name":"Northeastern University , , ,","place":["Shenyang, China, 110169"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yumo","family":"She","sequence":"additional","affiliation":[{"name":"Shengjing Hospital of China Medical University , , ,","place":["Shenyang, China, 110004"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0009-6470-8570","authenticated-orcid":true,"given":"Deliang","family":"Li","sequence":"additional","affiliation":[{"name":"Northeastern University , , ,","place":["Shenyang, China, 110169"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Haoyuan","family":"Wu","sequence":"additional","affiliation":[{"name":"The University of Hong Kong , , ,","place":["Hong Kong, China, 99999"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dianzhe","family":"Yang","sequence":"additional","affiliation":[{"name":"Northeastern University , , ,","place":["Shenyang, China, 110169"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hongbo","family":"Wang","sequence":"additional","affiliation":[{"name":"Northeastern University , , ,","place":["Shenyang, China, 110169"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2134-1536","authenticated-orcid":true,"given":"Ye","family":"Tian","sequence":"additional","affiliation":[{"name":"Northeastern University , , ,","place":["Shenyang, China, 110169"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"316","published-online":{"date-parts":[[2026,9,24]]},"reference":[{"key":"2026100915073952500_cit1","doi-asserted-by":"publisher","first-page":"509","DOI":"10.1038\/nature16521","article-title":"Fully Integrated Wearable Sensor Arrays for Multiplexed in Situ Perspiration Analysis","volume":"529","author":"Gao","year":"2016","journal-title":"Nature"},{"key":"2026100915073952500_cit2","doi-asserted-by":"publisher","first-page":"1105","DOI":"10.1038\/s41591-021-01339-0","article-title":"Wearable Sensors Enable Personalized Predictions of Clinical Laboratory Measurements","volume":"27","author":"Dunn","year":"2021","journal-title":"Nat.
