Traditionally, medical imaging is the most common means of evaluating the corrective effect of bracing during treatment. However, the imaging approach falls short in providing real\u2010time feedback, and the optimal corrective force remains unclear, potentially slowing the patient's recovery progress. To tackle these challenges, an all\u2010in\u2010one integrated array of pressure sensors and sEMG electrodes based on hierarchical MXene\/chitosan\/polydimethylsiloxane (PDMS)\/polyurethane sponge and MXene\/polyimide (PI) is developed. Benefiting from the microstructured electrodes and the modulus enhancement of PDMS, the sensor demonstrates a high sensitivity of 444.3 kPa<jats:sup>\u22121<\/jats:sup> and a broad linear detection range (up to 81.6\u00a0kPa). With the help of electrostatic attraction of chitosan and interface locking of PDMS, the pressure sensor achieves remarkable stability of over 100\u00a0000 cycles. Simultaneously, the sEMG electrodes offer exceptional stretchability and flexibility, functioning effectively at 60% strain, which ensures precise signal capture for various human motions. After integrating the developed all\u2010in\u2010one arrays into a commercial scoliosis brace, the system can accurately categorize human motion and predict Cobb angles aided by deep learning. This study provides real\u2010time insights into brace effectiveness and patient progress, offering new ideas for improving the efficiency of scoliosis treatment.<\/jats:p>","DOI":"10.1002\/smll.202404136","type":"journal-article","created":{"date-parts":[[2024,8,8]],"date-time":"2024-08-08T10:59:43Z","timestamp":1723114783000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":18,"title":["An All\u2010in\u2010One Array of Pressure Sensors and sEMG Electrodes for Scoliosis Monitoring"],"prefix":"10.1002","volume":"20","author":[{"given":"Weizhe","family":"Fan","sequence":"first","affiliation":[{"name":"Key Laboratory of Advanced Technologies of Materials (Ministry of Education) School of Materials Science and Engineering Southwest Jiaotong University  Chengdu Sichuan 610031 P.
