Here, carbon nanotube (CNT) films doped with various PVA fractions (CNT\/PVA) and ZnO nanowires (nano-ZnO) on zinc sheets were first fabricated by functionalized self-assembly and hydrothermal synthesis processes. A CNT\/PVA\/nano-ZnO flexible composite (CNT\/PVA\/ZnO) sandwiched with a zinc wafer was then prepared by the spin-coating method. The piezoresistive and\/or piezoelectric capabilities of the CNT\/PVA\/ZnO composite were comprehensively investigated under cyclic bending and impact loading after it was firmly adhered to a substrate (polypropylene sheet or mortar plate). The results show that the piezoresistive sensitivity and linear stability of the CNT\/PVA films doped with 20%, 50%, and 100% PVA during bending are 5.47%\/mm, 11.082%\/mm, and 11.95%\/mm and 2.3%, 3.42%, and 4.78%, respectively. The piezoelectric sensitivity, linear stability, and response accuracy of the CNT\/PVA\/ZnO composite under impulse loading are 4.87\u2009mV\/lbf, 3.42%, and 1.496\u2009ms, respectively. These merits support the use of CNT\/PVA\/ZnO as a piezoresistive and\/or piezoelectric compound sensor to monitor the static\/dynamic loads on concrete structures while it is attached.<\/jats:p>","DOI":"10.1038\/s41598-020-65771-x","type":"journal-article","created":{"date-parts":[[2020,6,1]],"date-time":"2020-06-01T10:03:14Z","timestamp":1591005794000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":57,"title":["Fabrication and Piezoresistive\/Piezoelectric Sensing Characteristics of Carbon Nanotube\/PVA\/Nano-ZnO Flexible Composite"],"prefix":"10.1038","volume":"10","author":[{"given":"Shuaichao","family":"Chen","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2916-0804","authenticated-orcid":false,"given":"Jianlin","family":"Luo","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiaoli","family":"Wang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Qiuyi","family":"Li","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Liucong","family":"Zhou","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chao","family":"Liu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chao","family":"Feng","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2020,6,1]]},"reference":[{"key":"65771_CR1","doi-asserted-by":"publisher","DOI":"10.1038\/ncomms2832","volume":"4","author":"G Schwartz","year":"2013","unstructured":"Schwartz, G. et al.
