Abstract

Organic electrochemical transistors (OECTs) have recently emerged as promising platforms for wearable sensors and computing devices. However, the scalable manufacturing of stretchable OECT remains a significant challenge, limiting their advancement in multicomponent sensing and massive data processing. Here, we present a photo-cross-linking strategy for the scalable fabrication of the intrinsically stretchable organic electrochemical transistors (IS-OECTs). This innovative approach allows for precise patterning of the organic semiconductor, specifically p(g2T-T). Notably, the photo-cross-linked p(g2T-T) maintains its integrity without cracking even under a 200% strain, ensuring consistent device performance under extreme strain conditions. By harnessing the nonlinear response and fading memory effect of the p(g2T-T)-based IS-OECT array, we developed a stretchable reservoir computing system that achieved impressive image recognition accuracies of 90.81% and 90.65% at 0% and 100% strains, respectively.

具有神经形态功能的内在可拉伸有机电化学晶体管的可扩展制造

有机电化学晶体管（OECTs）最近成为可穿戴传感器和计算设备的有前途的平台。然而，可伸缩OECT的可扩展制造仍然是一个重大挑战，限制了它们在多组分传感和海量数据处理方面的进步。在这里，我们提出了一种光交联策略，用于可扩展地制造本质可拉伸有机电化学晶体管（IS-OECTs）。这种创新的方法允许对有机半导体，特别是p（g2T-T）进行精确的图像化。值得注意的是，光交联的p（g2T-T）即使在200%的应变下也能保持其完整性而不开裂，确保在极端应变条件下保持一致的器件性能。通过利用基于p（g2T-T）的IS-OECT阵列的非线性响应和消退记忆效应，我们开发了一种可拉伸油藏计算系统，在0%和100%应变下，该系统的图像识别准确率分别达到了90.81%和90.65%。
