Abstract

Flexible sensors can be widely applied in the area of lightweight, wearable and intelligent electronic devices. In aerospace, for example, flexible sensors are suitable for measuring pressure in complex aircraft structures. In recent years, flexible sensors have been well developed; however, most of them lack circuit parts, meaning that the sensors have to be connected to an external electrical source. Additionally, the current traditional design limits their flexibility. Thus, this article proposes a self-powered flexible sensor based on PVDF nanofiber film, which is created through an efficient blow spinning method. The piezoelectric PVDF nanofiber films were prepared, and the flexible pressure sensor was assembled. The PVDF nanofiber film sensor showed good sensitivity and stability, and it can be applied for the detection of human physiological signals.
