Improvements in pressure-sensing performance, including in the output voltage, sensitivity and response time, can greatly expand their related applications; however, this remains challenging. Here, we report on a highly sensitive piezoelectric sensor with novel light-boosting pressure-sensing performance, based on a composite membrane of copper phthalocyanine (CuPC) and graphene oxide (GO) (CuPC@GO). Under light illumination, the CuPC@GO piezoelectric sensor demonstrates a remarkable increase in output voltage (381.17 mV, 50 kPa) and sensitivity (116.80 mV\/kPa, &lt;5 kPa), which are approximately twice and three times of that the sensor without light illumination, respectively. Furthermore, light exposure significantly improves the response speed of the sensor with a response time of 38.04 \u00b5s and recovery time of 58.48 \u00b5s, while maintaining excellent mechanical stability even after 2000 cycles. Density functional theory calculations reveal that increased electron transfer from graphene to CuPC can occur when the CuPC is in the excited state, which indicates that the light illumination promotes the electron excitation of CuPC, and thus brings about the high polarization of the sensor. Importantly, these sensors exhibit universal spatial non-contact adjustability, highlighting their versatility and applicability in various settings.<\/jats:p>","DOI":"10.3390\/ijms25126713","type":"journal-article","created":{"date-parts":[[2024,6,20]],"date-time":"2024-06-20T03:46:29Z","timestamp":1718855189000},"page":"6713","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Light-Boosting Highly Sensitive and Ultrafast Piezoelectric Sensor Based on Composite Membrane of Copper Phthalocyanine and Graphene Oxide"],"prefix":"10.3390","volume":"25","author":[{"given":"Jihong","family":"Wang","sequence":"first","affiliation":[{"name":"School of Physics, East China University of Science and Technology, Shanghai 200237, China"},{"name":"School of Materials Science and Engineering, East China University of Science and Technology, Shanghai 200237, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zhening","family":"Fang","sequence":"additional","affiliation":[{"name":"Center for Transformative Science, ShanghaiTech University, Shanghai 200237, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Wenhao","family":"Liu","sequence":"additional","affiliation":[{"name":"School of Physics, East China University of Science and Technology, Shanghai 200237, China"},{"name":"School of Materials Science and Engineering, East China University of Science and Technology, Shanghai 200237, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Liuyuan","family":"Zhu","sequence":"additional","affiliation":[{"name":"School of Physics, East China University of Science and Technology, Shanghai 200237, China"},{"name":"School of Materials Science and Engineering, East China University of Science and Technology, Shanghai 200237, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Qiubo","family":"Pan","sequence":"additional","affiliation":[{"name":"School of Physics, East China University of Science and Technology, Shanghai 200237, China"},{"name":"School of Materials Science and Engineering, East China University of Science and Technology, Shanghai 200237, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3913-3081","authenticated-orcid":false,"given":"Zhen","family":"Gu","sequence":"additional","affiliation":[{"name":"Key Laboratory of Smart Manufacturing in Energy Chemical Process Ministry of Education, East China University of Science and Technology, Shanghai 200237, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Huifeng","family":"Wang","sequence":"additional","affiliation":[{"name":"Key Laboratory of Smart Manufacturing in Energy Chemical Process Ministry of Education, East China University of Science and Technology, Shanghai 200237, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yingying","family":"Huang","sequence":"additional","affiliation":[{"name":"School of Physics, East China University of Science and Technology, Shanghai 200237, China"},{"name":"School of Materials Science and Engineering, East China University of Science and Technology, Shanghai 200237, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Haiping","family":"Fang","sequence":"additional","affiliation":[{"name":"School of Physics, East China University of Science and Technology, Shanghai 200237, China"},{"name":"School of Materials Science and Engineering, East China University of Science and Technology, Shanghai 200237, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2024,6,18]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"37","DOI":"10.1038\/s41551-018-0300-4","article-title":"Bioresorbable pressure sensors protected with thermally grown silicon dioxide for the monitoring of chronic diseases and healing processes","volume":"3","author":"Shin","year":"2019","journal-title":"Nat.
