DNA-Assisted β‑phase Nucleation and Alignment of Molecular Dipoles in PVDF Film: A Realization of Self-Poled Bioinspired Flexible Polymer Nanogenerator for Portable Electronic Devices
A flexible nanogenerator (NG) is
fabricated with a polyÂ(vinylidene fluoride) (PVDF) film, where deoxyribonucleic
acid (DNA) is the agent for the electroactive β-phase nucleation.
Denatured DNA is co-operating to align the molecular −CH<sub>2</sub>/–CF<sub>2</sub> dipoles of PVDF causing piezoelectricity
without electrical poling. The NG is capable of harvesting energy
from a variety of easily accessible mechanical stress such as human
touch, machine vibration, football juggling, and walking. The NG exhibits
high piezoelectric energy conversion efficiency facilitating the instant
turn-on of several green or blue light-emitting diodes. The generated
energy can be used to charge capacitors providing a wide scope for
the design of self-powered portable devices
