Fabrication of Nanofiber Flexible Pressure Sensor and Application in Human Motion Monitoring

Abstract

Nowadays, people are increasingly concerned about body mass index and monitoring human movement has become a necessity for most people, and the nanofiber flexible pressure sensor fully meets people’s needs, so the research on a nanofiber flexible pressure sensor is very meaningful. The purpose of this article is to study a sensor with high sensitivity of the nanofiber material of PVDF thin films. And this article conducts experiments through the prepared pressure sensor and other sensors, which test the three movements of humans taking off, squatting, and running. This article calculates the correct recognition rate, false-negative rate, and false-positive rate and then compares them. The experimental data show that the correct recognition rate of PVDF thin-film nanomaterials is as high as 90%, and the recognition rate of non-nanomaterial pressure sensors is even less than 80%. Nanomaterial pressure sensors will have more room for development.
