Here, we report a porous poly(vinylidene fluoride-hexafluoropropylene) (PVDF-HFP) nanofibrous piezoelectric sensor integrating partially reduced graphene oxide (rGO) and lead-free (Ba0.85Ca0.15)(Ti0.9Zr0.1)O3(BCZT), fabricated by electrospinning and thermal annealing. The synergistic effects of rGO and BCZT promote \u03b2-phase formation, interfacial polarization, and charge transfer, resulting in enhanced piezoelectric output and low-pressure sensing performance. The optimized sensor delivers an output voltage of 11.25 V, a sensitivity of 6.44 V kPa\u20131 below 0.5 kPa, a detection limit below 12 Pa, and a rapid response time of 16.5 ms. The device was further integrated into a tactile\u2013visual feedback interface for non-auditory rhythm perception. Benefiting from the distinct temporal features of the piezoelectric signals, six tactile interaction modes were accurately decoded by a one-dimensional convolutional neural network (1D CNN), achieving 100% accuracy on the test. This work provides an interface-engineering strategy for high-performance flexible piezoelectric sensors and advances their use in intelligent tactile perception and multimodal human\u2013machine interaction.<\/jats:p>","DOI":"10.1021\/acsami.6c12746","type":"journal-article","created":{"date-parts":[[2026,10,15]],"date-time":"2026-10-15T17:01:33Z","timestamp":1792083693000},"page":"57847-57856","source":"Crossref","is-referenced-by-count":0,"title":["Flexible PVDF-HFP Piezoelectric Nanofibers with In Situ rGO and BCZT for High-Sensitivity Tactile Sensing and Haptic-Visual Feedback"],"prefix":"10.1021","volume":"18","author":[{"given":"Wen","family":"Li","sequence":"first","affiliation":[{"name":"Henan University of Technology , , ,","place":["Zhengzhou, China, 450001"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0001-2642-6427","authenticated-orcid":true,"given":"Shenglin","family":"Kang","sequence":"additional","affiliation":[{"name":"Chongqing University , , ,","place":["Chongqing, China, 400044"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zijie","family":"Wei","sequence":"additional","affiliation":[{"name":"Chongqing University , , ,","place":["Chongqing, China, 400044"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiaosong","family":"Li","sequence":"additional","affiliation":[{"name":"Chongqing University , , ,","place":["Chongqing, China, 400044"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shukun","family":"Li","sequence":"additional","affiliation":[{"name":"Henan University of Technology , , ,","place":["Zhengzhou, China, 450001"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Li","family":"Wang","sequence":"additional","affiliation":[{"name":"Henan University of Technology , , ,","place":["Zhengzhou, China, 450001"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ping","family":"Wang","sequence":"additional","affiliation":[{"name":"Chongqing University , , ,","place":["Chongqing, China, 400044"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2653-2868","authenticated-orcid":true,"given":"Lu-Qi","family":"Tao","sequence":"additional","affiliation":[{"name":"Tsinghua University , , ,","place":["Beijing, China, 100084"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"316","published-online":{"date-parts":[[2026,10,15]]},"reference":[{"issue":"6690","key":"2026102914073187600_cit1","doi-asserted-by":"publisher","first-page":"1492","DOI":"10.1126\/science.adj1946","article-title":"Biodegradable ferroelectric molecular crystal with large piezoelectric response","volume":"383","author":"Zhang","year":"2024","journal-title":"Science"},{"issue":"33","key":"2026102914073187600_cit2","doi-asserted-by":"publisher","DOI":"10.1002\/adma.202405308","article-title":"Advances in Piezoelectret Materials-Based Bidirectional Haptic Communication Devices","volume":"36","author":"Gong","year":"2024","journal-title":"Adv.
