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
