However, conventional flexible foam piezoresistive sensors often struggle to simultaneously achieve high sensitivity, a wide pressure detection range, fast response and long-term stability. This paper employed a glucose-based sugar-templating method to fabricate a fine-pore (50 \u03bcm) foam structure complemented by a dual-filler strategy to enhance overall performance. A robust porous conductive network was constructed by embedding zinc oxide (ZnO) and multi-walled carbon nanotubes (MWCNTs) into a polydimethylsiloxane (PDMS) matrix. The resulting sensor exhibits outstanding piezoresistive properties, featuring a wide linear detection range (0\u201380% strain) and a high sensitivity of 9.02 kPa\u22121 within the 0\u201310 kPa pressure range. It demonstrates rapid response\/recovery times of 50\/70 ms and maintains stable output performance even after 5000 compression cycles at 300 kPa. The sensor also exhibits negligible environmental interference and excellent long-term stability. When attached to finger joints, feet soles, or the throat, the sensor enables functions such as finger bending recognition, race-walking violation discrimination, gait analysis, and vocal fold vibration recognition, thereby demonstrating its considerable potential for application in human\u2013computer interaction and human motion detection.<\/jats:p>","DOI":"10.3390\/s26051724","type":"journal-article","created":{"date-parts":[[2026,3,9]],"date-time":"2026-03-09T11:06:52Z","timestamp":1773054412000},"page":"1724","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["A Flexible Piezoresistive Sensor Based on ZnO\/MWCNTs\/PDMS Composite Foam with Overall Performance Trade-Offs"],"prefix":"10.3390","volume":"26","author":[{"given":"Jun","family":"Zheng","sequence":"first","affiliation":[{"name":"College of Optical, Mechanical and Electrical Engineering, Zhejiang A&F University, Hangzhou 311300, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wenting","family":"Xu","sequence":"additional","affiliation":[{"name":"College of Optical, Mechanical and Electrical Engineering, Zhejiang A&F University, Hangzhou 311300, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wen","family":"Ding","sequence":"additional","affiliation":[{"name":"College of Optical, Mechanical and Electrical Engineering, Zhejiang A&F University, Hangzhou 311300, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yalong","family":"Li","sequence":"additional","affiliation":[{"name":"School of Physical Science and Technology, Ningbo University, Ningbo 315211, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Binyou","family":"Xie","sequence":"additional","affiliation":[{"name":"College of Optical, Mechanical and Electrical Engineering, Zhejiang A&F University, Hangzhou 311300, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jinhui","family":"Xu","sequence":"additional","affiliation":[{"name":"College of Optical, Mechanical and Electrical Engineering, Zhejiang A&F University, Hangzhou 311300, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kang","family":"Li","sequence":"additional","affiliation":[{"name":"College of Optical, Mechanical and Electrical Engineering, Zhejiang A&F University, Hangzhou 311300, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Liang","family":"Chen","sequence":"additional","affiliation":[{"name":"School of Physical Science and Technology, Ningbo University, Ningbo 315211, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0009-9653-9898","authenticated-orcid":false,"given":"Yan","family":"Fan","sequence":"additional","affiliation":[{"name":"College of Optical, Mechanical and Electrical Engineering, Zhejiang A&F University, Hangzhou 311300, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Songwei","family":"Zeng","sequence":"additional","affiliation":[{"name":"College of Optical, Mechanical and Electrical Engineering, Zhejiang A&F University, Hangzhou 311300, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,3,9]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"107171","DOI":"10.1016\/j.compositesa.2022.107171","article-title":"High-Performance and Superhydrophobic Piezoresistive Pressure Sensor Based on Mountain Ridge-like Microstructure by Silver Nanoparticles and Reduced Graphene Oxide","volume":"162","author":"Chen","year":"2022","journal-title":"Compos.
