Triboelectric nanogenerators (TENGs) are an emerging energy-harvesting technology that converts mechanical motion into electricity. A recent review in AIMS Materials Science highlights how laser surface processing can significantly enhance TENG performance by enabling fast, precise, and scalable surface patterning.
The paper summarizes several laser-based approaches—laser-induced graphene (LIG), laser ablation, laser carbonization, and laser-induced copper—each tailored to modify surface micro/nanostructures for improved charge generation and durability. These techniques allow controlled changes in surface morphology and properties at multiple scales, which directly impacts output power and stability.
The authors also discuss key challenges such as scalability, cost, and long-term stability, and outline future directions for integrating laser processing into high-performance, mass-producible TENG systems.
