Electrical performance of paper-based hygroelectric generator flattened by non-traditional press

Abstract

The high cost of calendering presses limits the scalability of certain hygroelectric generator fabrication methods, highlighting the need for a more affordable alternative. This study investigates the electrical performance of a paper-based hygroelectric generator (ERG-HEG). The HEG utilizes three non-traditional approaches: flat iron, rolling pin, and metal plate to simulate the function of a calender machine and evaluate its effectiveness in enhancing the generator's electrical output. Results indicate significant fluctuations in electrical output across all methods. These inconsistencies are attributed to non-uniform pressure application, which affects the formation of conductive pathways in the ERG coating. The initial results highlights the critical role of uniform compression in achieving optimal conductivity and suggests that future efforts should focus on developing a standardized calendering process to enhance scalability. The findings provide valuable insights for optimizing the fabrication process of ERG-HEG devices.
