实现神经功能的柔性有机电子皮肤具有广泛的应用前景，如皮肤假肢，神经机器人，生物电子学，人机交互（HRI）等。在这里，我们报道了一种由全有机材料组成的全橡胶突触晶体管的发展，它显示了生物突触中存在的独特突触特性。这些突触特征在机械拉伸下仍保持30%。我们进一步开发了一种全橡胶格式的神经电子皮肤，该皮肤基于压敏橡胶的两个机械感受器（用于突触增强或抑制）和一个全有机突触晶体管。通过将触觉信号转换为莫尔斯电码，兴奋性突触后电流（EPSC）信号的增强和抑制使人类前臂上的神经电子皮肤能够与机器人手进行交流。对材料、器件及其特性的集体研究揭示了全有机突触晶体管和神经电子皮肤的基本方面和适用性。
Neurologic function implemented soft organic electronic skin holds promise for wide range of applications, such as skin prosthetics, neurorobot, bioelectronics, human-robotic interaction (HRI), etc. Here, we report the development of a fully rubbery synaptic transistor which consists of all-organic materials, which shows unique synaptic characteristics existing in biological synapses. These synaptic characteristics retained even under mechanical stretch by 30%. We further developed a neurological electronic skin in a fully rubbery format based on two mechanoreceptors (for synaptic potentiation or depression) of pressure-sensitive rubber and an all-organic synaptic transistor. By converting tactile signals into Morse Code, potentiation and depression of excitatory postsynaptic current (EPSC) signals allow the neurological electronic skin on a human forearm to communicate with a robotic hand. The collective studies on the materials, devices, and their characteristics revealed the fundamental aspects and applicability of the all-organic synaptic transistor and the neurological electronic skin.
