Abstract

We report on the mechanical fatigue behavior of printed, organic, thin-film transistors (OTFTs) based on a polymer semiconductor, investigated by repeatedly applying strain to the flexible OTFT devices and assessing their electrical characteristics after 60,000 bending cycles. As part of our investigation, we established that the rates of reduction in source/drain currents in the OTFT device depended on bending directions. Our improved understanding of the mechanical fatigue behavior of the flexible printed OTFT devices provides valuable insights into their employment in practical flexible electronics applications.

摘要

我们报告了基于聚合物半导体的印刷有机薄膜晶体管（OTFT）的机械疲劳行为，通过对柔性OTFT器件反复施加应变并在60,000次弯曲循环后评估其电学特性来进行研究。作为我们研究的一部分，我们确定了OTFT器件中源极/漏极电流的降低速率取决于弯曲方向。我们对柔性印刷OTFT器件机械疲劳行为的进一步理解为其在实际柔性电子应用中的使用提供了有价值的见解。
