This study investigates the mechanical–electrical conversion properties of biomaterials as a layer in Bio-Based Triboelectric Nanogenerators (B-TENGs) and characterizes their output performance for self-powered sensor systems. The main focus of the B-TENG design is on material and structural modifications, with experiments conducted to compare the output of B-TENGs using banana peel as the tribopositive material. The triboelectricity method employed is the sliding rotational mode, with a circular vane design featuring an overall diameter of 46.23 cm2 and a constant speed of 10 Hz. The study examines the effects of various parameters on the B-TENG output, including the number of vanes (3, 4, 5), material thickness (0.1, 0.2, 0.3 cm), and different tribonegative materials (PTFE, PE, PVC). The results demonstrate a maximum open-circuit voltage of 26.8 V, power output of 0.38 mW, and power density of 7.31 μW/cm2. The findings suggest that the performance of B-TENGs can be further improved by incorporating more vanes, increasing material thickness, and exploring additional types of bio-based materials. This study contributes to the development of sustainable and efficient self-powered sensor systems by optimizing the mechanical–electrical conversion properties of bio-based materials in triboelectric nanogenerators.

摘要

This study investigates the mechanical–electrical conversion properties of biomaterials as a layer in Bio-Based Triboelectric Nanogenerators (B-TENGs) and characterizes their output performance for self-powered sensor systems. The main focus of the B-TENG design is on material and structural modifications, with experiments conducted to compare the output of B-TENGs using banana peel as the tribopositive material. The triboelectricity method employed is the sliding rotational mode, with a circular vane design featuring an overall diameter of 46.23 cm2 and a constant speed of 10 Hz. The study examines the effects of various parameters on the B-TENG output, including the number of vanes (3, 4, 5), material thickness (0.1, 0.2, 0.3 cm), and different tribonegative materials (PTFE, PE, PVC). The results demonstrate a maximum open-circuit voltage of 26.8 V, power output of 0.38 mW, and power density of 7.31 μW/cm2. The findings suggest that the performance of B-TENGs can be further improved by incorporating more vanes, increasing material thickness, and exploring additional types of bio-based materials. This study contributes to the development of sustainable and efficient self-powered sensor systems by optimizing the mechanical–electrical conversion properties of bio-based materials in triboelectric nanogenerators.
