Her thesis is ‘’

Flexible piezoelectric Nano Generator based on PVDF‘

During the COVID 2019 period, she worked hard and finished her thesis and got her BEng degree in Tiangong University.

Due to its high piezoelectric properties, the film Polyvinylidene fluoride (PVDF) was widely investigated as a sensor and transducer content. PVDF films need a mechanical operation, stretching or poling to enable certain properties. In this paper we report on a force sensor with excellent versatility and breathability based on PVDF fabrics,To be used as a basic sensor linked to humans. Using an electrospinning unit, PVDF nanofibrous fabrics were prepared and characterized by scanning electron microscopy (SEM), FTIR spectroscopy, and X-ray diffraction. Preliminary force sensors were developed, and excellent sensitivity and response to external mechanical forces was demonstrated.This means that promising applications for sensing the pressure of the fabric, blood pressure, pulse rate, respiration rate and unintended eff
