Performance investigation of piezoelectric PVDF-TrFE polymer for it's mechanical and electrical response and use as vibration sensor
Piezoelectric polymers, such as PVDF-TrFE, are increasingly studied for their potential to replace traditional ceramic based piezoelectric materials due to their flexibility, ease of processing, and strong adhesion properties. This study focuses on PVDF-TrFE with a 75/25 molar concentration, …

Polarization-induced transport in ferroelelctric organic field-effect transistors
… of the polymer, poly(vinylidene fluoride) (PVDF)), has been known for over 45 years. However, its role in interfacial transport in organic/polymeric FETs is not that well understood. PVDF and its copolymer, polyvinylidene fluoride-trifluoroethylene (PVDF-TrFE), as a dielectric in organic …

Development to a Flexible Surface Acoustic Wave Sensor for Strain Sensing
… as a reinforcement into polyvinylidene fluoride (PVDF) polymer matrix in the 0-3 direction. This enables the substrate to attain enhanced piezoelectric properties along with improved mechanical strength. PVDF is dissolved in a strong polar solvent such as N, N- dimethyl sulfoxide to which 50 wt. % …
