A research team from Amir Kabir University of Technology has developed a novel hybrid piezoelectric structure based on poly (vinylidene difluoride) nanofibers (PVDF NFs) and zinc oxide nanorods (ZnO NRs) which eliminate the need for post poling treatment in such hybrid structures.

According to an ISCA report, in this research which is available in RSC Advances, researchers discussed about the piezoelectric performance of three nanogenerators that was evaluated under periodic deformation at low frequency.

“The output power of the hybrid structure was found to be enhanced compared to pristine ZnO NRs and PVDF NFs nanogenerators. Such simple hybrid devices that do not need to complicated post poling treatment are more efficient than previous hybrid PVDF/ZnO nanogenerators for practical application.

“This improved piezoelectric nanogenerator is expected to enable various applications in the field of self-powered devices and wearable energy harvesting to harvest mechanical energy from the human activities. “

The research has been carried out by Parisa Fakhri, led by Dr. Roohollah Bagherzadeh and Dr. Masoud Latifi in cooperation with Dr. Mohammad Kashfi from University of Ayatollah Borujerdi, Babak Amini and Neda Yavari.
