Abstract
This study explores the utilization of fabricated piezoelectric polyvinylidene fluoride nanofiber (NF-PVDF) materials in wearable electronic sensing applications by investigating their current-voltage (\(\:I-V\)) characteristics under controlled ultra-low-frequency excitation forces. The results demonstrate a significant power harvesting capability, achieving an output power of 0.12 µW/mm2 at an operating point of 5.04 V and 7.7 µA. Additionally, the piezoelectric harvester was integrated into a charging-discharge circuit alongside a rectifier capacitor and a typical IoT wearable sensor, leveraging the advantages of a flexible substrate. Experimental measurements of the charging and discharging curves confirm the effective energy management of the system, indicating a robust potential for deployment in real-world sensing applications. These findings highlight the promising application of NF-PVDF in sustainable energy harvesting for next-generation wearable technologies.

Energy is the single most valuable resource for human activity and the basis for all human progress. Materials play a key role in enabling technologies that can offer promising solutions to achieve renewable and sustainable energy pathways for the future.
Materials for Renewable and Sustainable Energy has been established to be the world''s foremost interdisciplinary forum for publication of research on all aspects of the study of materials for the deployment of renewable and sustainable energy technologies. The journal covers experimental and theoretical aspects of materials and prototype devices for sustainable energy conversion, storage, and saving, together with materials needed for renewable fuel production. It publishes reviews, original research articles, rapid communications, and perspectives. All manuscripts are peer-reviewed for scientific quality.
Topics include:
1. MATERIALS for renewable energy storage and conversion: Batteries, Supercapacitors, Fuel cells, Hydrogen storage, and Photovoltaics and solar cells.
2. MATERIALS for renewable and sustainable fuel production: Hydrogen production and fuel generation from renewables (catalysis), Solar-driven reactions to hydrogen and fuels from renewables (photocatalysis), Biofuels, and Carbon dioxide sequestration and conversion.
3. MATERIALS for energy saving: Thermoelectrics, Novel illumination sources for efficient lighting, and Energy saving in buildings.
4. MATERIALS modeling and theoretical aspects.
5. Advanced characterization techniques of MATERIALS
Materials for Renewable and Sustainable Energy is committed to upholding the integrity of the scientific record. As a member of the Committee on Publication Ethics (COPE) the journal will follow the COPE guidelines on how to deal with potential acts of misconduct. Authors should refrain from misrepresenting research results which could damage the trust in the journal and ultimately the entire scientific endeavor. Maintaining integrity of the research and its presentation can be achieved by following the rules of good scientific practice as detailed here: https://www.springer.com/us/editorial-policies
