The performance of vacuum insulation panels (VIPs) is greatly determined by their internal vacuum, which is difficult to maintain constant for a long period of time, thus leading to their premature aging. This degradation is mainly caused by the underlying gas and moisture permeation under an extreme environment or from the residual material left inside during the manufacturing process. Hence, the development of smart pressure sensors capable of identifying minute fluctuations in the internal pressure at an initial stage is currently highly desirable in the industry. In the present study, the electrospinning technique was used for the fabrication of poly(vinylidene fluoride-trifluoroethylene) P(VDF-TrFE) and graphene-oxide-modified poly(vinylidene fluoride-trifluoroethylene) GO-P(VDF-TrFE) fiber membranes for piezoelectric pressure-sensing applications. The conventional interdigitated electrode was successfully deposited on the fibrous structure with high continuity in the fingers. The thermal stability and compatibility of the prepared structures were ascertained by performing the thermal characterization. The developed devices revealed high electric output when exposed to the pressure. The GO-P(VDF-TrFE) smart fiber-based device offered admirable response time (0.282 s) and high linearity of R² = 0.99294, respectively. Our findings will lay a foundation for the establishment of future wireless smart structures capable of detecting small internal pressure (≤ 10 Pa) in many devices such as VIPs and other products even after their installation in building structures.

真空隔热板（VIP）的性能在很大程度上取决于其内部真空度，很难长期保持恒定，从而导致其过早老化。这种降解主要是由于极端环境下的底层气体和水分渗透或制造过程中残留在内部的残留材料引起的。因此，当前在工业上非常需要开发能够在初始阶段识别内部压力的微小波动的智能压力传感器。在目前的研究中，静电纺丝技术被用于制造聚偏二氟乙烯-三氟乙烯P（VDF-TrFE）和氧化石墨烯改性的聚偏二氟乙烯-三氟乙烯GO-P（VDF-TrFE）纤维膜以进行压电压力传感应用程序。常规的叉指电极成功地以高连续性沉积在手指上的纤维结构上。通过进行热表征来确定所制备结构的热稳定性和相容性。所开发的设备在承受压力时显示出高电输出。GO-P（VDF-TrFE）基于智能光纤的设备可提供出色的响应时间（0.282 s）和高线性度 通过进行热表征来确定所制备结构的热稳定性和相容性。所开发的设备在承受压力时显示出高电输出。GO-P（VDF-TrFE）基于智能光纤的设备可提供出色的响应时间（0.282 s）和高线性度 通过进行热表征来确定所制备结构的热稳定性和相容性。所开发的设备在承受压力时显示出高电输出。GO-P（VDF-TrFE）基于智能光纤的设备可提供出色的响应时间（0.282 s）和高线性度R ² 分别为0.99294。我们的发现将为建立未来的无线智能结构奠定基础，即使它们安装在建筑结构中，也能够检测许多设备（例如VIP和其他产品）中的较小内部压力（≤10 Pa）。
