Cold rolled robust metal assisted triboelectric nanogenerator for extremely durable operation

摘要: Abstract The triboelectric nanogenerator (TENG), which generates electricity by means of contact electrification, has eminent advantages such as simple operation mechanism and diversity material choice. recent rapid development the TENG makes one promising energy harvesters in near future but its durable with enhanced output performance still remains most critical challenges. In this study, we suggest a novel strategy to develop robust employing cold-rolled metal layer layers. robustness is confirmed directly investigating hardness. developed exhibits no significant degradation even after extremely high number cycles ( ∼ 1,500,000 cycles). As long-term durability essential for practical utilization, present would provide basis semi-permanent next-generation TENGs.
