Piezoelectric flexible generator based on Mn-doped ZnO/PVDF composite films for energy harvesting application
A flexible piezoelectric energy harvesting device was manufactured using Mn-doped ZnO (MnZ)/poly (vinylidene fluoride) (PVDF) composite film of various proportions of MnZ particles (5 wt%, 10 wt%, 20 wt% and 30 wt%) within the PVDF matrix. The phase formation, crystallinity and morphological characteristics of the fabricated composite films were analysed with the help of Fourier transform infrared (FTIR), X-ray diffraction (XRD), and Scanning Electron Microscopy (SEM). The piezoelectric performance of the constructed piezoelectric generator (PEG) device was measured by applying force on its surface which produced a significantly high open-circuit voltage of 344V and power density of 4.53 mW/cm2. Besides, these lead-free composite devices demonstrated remarkable sensitivity for human body motion detection in punching, finger bending, and wrist bending. Furthermore, practical usage of the fabricated PEG device was shown by powering devices like wristwatches, digital thermometers and glowing 20 light-emitting diodes (LEDs) of different colours.
期刊介绍:
Current Applied Physics (Curr. Appl. Phys.) is a monthly published international journal covering all the fields of applied science investigating the physics of the advanced materials for future applications.
Other areas covered: Experimental and theoretical aspects of advanced materials and devices dealing with synthesis or structural chemistry, physical and electronic properties, photonics, engineering applications, and uniquely pertinent measurement or analytical techniques.
Current Applied Physics, published since 2001, covers physics, chemistry and materials science, including bio-materials, with their engineering aspects. It is a truly interdisciplinary journal opening a forum for scientists of all related fields, a unique point of the journal discriminating it from other worldwide and/or Pacific Rim applied physics journals.
Regular research papers, letters and review articles with contents meeting the scope of the journal will be considered for publication after peer review.
The Journal is owned by the Korean Physical Society.
