AI Technical Summary
Triboelectric generators using same-material polymer surfaces suffer from low energy output due to a lack of driving force for charge separation, limiting their practical application and environmental impact through waste recycling.
A laminate composition comprising alternating layers of fibers with varying diameters, where at least a portion of the first set of fibers is 2 to 10 times larger than the second set, and fibers in one layer are interwoven or extend into adjacent layers, creating a triboelectric generator with same-material elements that generate electricity through contact and separation.
The solution enhances energy output and simplifies production, enabling practical applications and recycling of ubiquitous polymers into energy-harvesting products, addressing the limitations of conventional triboelectric generators.
