To circumvent the limitations of existing sensors in maintaining high responsiveness across extensive pressure ranges, herein, a novel flexible capacitive pressure sensor is developed based on a 3D porous ionogel foam composite (IL\/EG\/PVA@MF) coupled with a planar electrode array. This device leverages the synergistic structural engineering of the 3D hyperelastic melamine foam (MF) skeleton and the pressure-regulated fringe-field distribution and iontronic interfacial polarization of the porous ionogel. Experimental evaluations demonstrate that the sensor achieves a high normalized sensitivity of 62.45 kPa\u22121 (2\u201310 kPa) and maintains reliable piecewise linear sensing performance across a broad working range of 0\u201350 kPa, accompanied by a rapid response time of within 8 ms. Furthermore, the sensor exhibits outstanding performance consistency after 6000 compression-release cycles at 50 kPa, verifying its good mechanical durability. In practical applications, the device can monitor diverse physiological signals with high fidelity, ranging from subtle radial artery pulses to large-scale joint movements and specific coughing patterns, underscoring its broad potential for integrated wearable systems and intelligent healthcare.<\/jats:p>","DOI":"10.3390\/mi17080983","type":"journal-article","created":{"date-parts":[[2026,8,20]],"date-time":"2026-08-20T12:57:53Z","timestamp":1787230673000},"page":"983","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["A Flexible Capacitive Pressure Sensor with Broad-Range High Sensitivity Based on 3D Porous Ionogel for Wearable Health Monitoring"],"prefix":"10.3390","volume":"17","author":[{"ORCID":"https:\/\/orcid.org\/0009-0007-0134-6328","authenticated-orcid":false,"given":"Yi","family":"Chen","sequence":"first","affiliation":[{"name":"State Key Laboratory of Extreme Environment Optoelectronic Dynamic Testing Technology and Instrument, North University of China, Taiyuan 030051, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xuedan","family":"Xie","sequence":"additional","affiliation":[{"name":"Department of Electrical and Control Engineering, Shanxi Institute of Energy, Jinzhong 030600, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yonghua","family":"Wang","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Extreme Environment Optoelectronic Dynamic Testing Technology and Instrument, North University of China, Taiyuan 030051, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2116-5157","authenticated-orcid":false,"given":"Dan","family":"Liu","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Extreme Environment Optoelectronic Dynamic Testing Technology and Instrument, North University of China, Taiyuan 030051, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,8,20]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"2110417","DOI":"10.1002\/adfm.202110417","article-title":"Ionic flexible sensors: Mechanisms, materials, structures, and applications","volume":"32","author":"Zhao","year":"2022","journal-title":"Adv.
