Stretchable organic transistors possess great potential in a variety of emerging areas such as biomedical electronics, wearable gadgets and smart skin. Here, stretchable vertical organic field effect transistor (s-VOFET) is developed for the first time, which exhibits low working voltage (−0.5 V), high current density (5.19 mA/cm²) and excellent stretching stability. More interesting, the on state current increased by 68.5% and the sub-threshold swing decreased by 25.2% with the increase of the strain to 20%. It is ascribed to the enhanced face-on orientation of π-π stacking in semiconductor film by stretching strain, providing more efficient pathways for vertical charge transport. Meanwhile, simulation results demonstrate that stretching strain can enhance gate field controllability to charge carriers, resulting in enhanced charge transport and accumulation. Moreover, stretchable vertical synaptic transistor (s-VST) is fabricated by replacing cross-linked PVA with ion gel, which exhibits stable synaptic characteristics even with 60% stretching strain. Noticeably, coupling triboelectric nanogenerator (TENG) and synaptic transistor leads to a new field of triboelectric, which enables the direct interactions between environmental perception data and human-machine interfacing. Therefore, a stretchable self-powered neurologically integrated artificial tactile pathway is constructed using TENG and s-VST, which successfully conducts touch wireless communication and sensory skin touch-interaction. This work provides critical guidelines for the development of high performance stretchable electronic devices and a new platform for enabling neurological functions in stretchable electronics.

可拉伸有机晶体管在生物医学电子、可穿戴设备和智能皮肤等各种新兴领域具有巨大潜力。在这里，首次开发了可拉伸垂直有机场效应晶体管（s-VOFET），它具有低工作电压（-0.5 V）、高电流密度（5.19 mA/cm ²) 和优异的拉伸稳定性。更有趣的是，随着应变增加到 20%，导通电流增加了 68.5%，亚阈值摆幅减少了 25.2%。这归因于通过拉伸应变增强了半导体薄膜中 π-π 堆叠的正面取向，为垂直电荷传输提供了更有效的途径。同时，模拟结果表明拉伸应变可以增强对电荷载流子的栅极场可控性，从而增强电荷传输和积累。此外，可拉伸垂直突触晶体管（s-VST）是通过用离子凝胶代替交联的 PVA 制成的，即使在 60% 的拉伸应变下也表现出稳定的突触特性。值得注意的是，摩擦纳米发电机（TENG）和突触晶体管的耦合导致了摩擦电的新领域，这使得环境感知数据和人机接口之间的直接交互成为可能。因此，使用 TENG 和 s-VST 构建了可拉伸的自供电神经集成人工触觉通路，成功地进行了触摸无线通信和感觉皮肤触摸交互。这项工作为开发高性能可拉伸电子设备和实现可拉伸电子设备神经功能的新平台提供了关键指导。
