Abstract

Based on the principle of low-carbon economy, the fabrication and design of flexible sensors with self-power and low manufacturing cost remain challenges in smart wearable electronic systems. In this study, we fabricated a self-powered piezoelectric sensor based on sustainable textiles that can be rapidly manufactured by a functional spray solution made of fluorinated polyimide (FPI) with high solubility in acetone. The as-prepared piezoelectric sensor shows excellent flexibility and enhanced intelligent sensor monitoring capabilities through incorporating barium titanate nanoparticles (BTO), while also achieving the recycling of discarded textiles. The piezoelectric sensor derived from piezoelectric spray with 20 wt% BTO concentration exhibits high piezoelectricity with output voltages reaching up to 80 V for human body detection. Furthermore, the integration of the sensor with an IoT chip-based wireless signal transmission system enables remote monitoring and emergency assistance via mobile devices, facilitating its application in smart electronic systems with great potential for application.

基于可持续纺织品的自供电传感器的压电喷涂快速制造

基于低碳经济原理，制造和设计具有自供电能力和低制造成本的柔性传感器是智能可穿戴电子系统面临的挑战。在这项研究中，我们制造了一种基于可持续纺织品的自供电压电传感器，该传感器可以通过在丙酮中具有高溶解度的氟化聚酰亚胺（FPI）制成的功能喷雾溶液快速制造。制备的压电传感器通过加入钛酸钡纳米颗粒（BTO）显示出优异的灵活性和增强的智能传感器监测能力，同时还实现了废弃纺织品的回收利用。由BTO浓度为20 wt%的压电喷雾制成的压电传感器具有高压电性，输出电压高达80 V，可用于人体检测。此外，该传感器与基于物联网芯片的无线信号传输系统集成，可以通过移动设备进行远程监控和紧急救援，有利于其在具有巨大应用潜力的智能电子系统中的应用。
