Artificial skin that simultaneously mimics sensory feedback and mechanical properties of natural skin holds substantial promise for next-generation robotic and medical devices. However, achieving such a biomimetic system that can seamlessly integrate with the human body remains a challenge. Through rational design and engineering of material properties, device structures, and system architectures, we realized a monolithic soft prosthetic electronic skin (e-skin). It is capable of multimodal perception, neuromorphic pulse-train signal generation, and closed-loop actuation. With a trilayer, high-permittivity elastomeric dielectric, we achieved a low subthreshold swing comparable to that of polycrystalline silicon transistors, a low operation voltage, low power consumption, and medium-scale circuit integration complexity for stretchable organic devices. Our e-skin mimics the biological sensorimotor loop, whereby a solid-state synaptic transistor elicits stronger actuation when a stimulus of increasing pressure is applied.

由单片集成、低电压、柔软电子皮肤体现的神经形态感觉运动环路

同时模仿天然皮肤的感觉反馈和机械特性的人造皮肤为下一代机器人和医疗设备带来了巨大的希望。然而，实现这样一个能够与人体无缝集成的仿生系统仍然是一个挑战。通过对材料特性、器件结构和系统架构的合理设计和工程，我们实现了整体软假体电子皮肤（e-skin）。它能够进行多模态感知、神经形态脉冲序列信号生成和闭环驱动。利用三层高介电常数弹性电介质，我们实现了与多晶硅晶体管相当的低亚阈值摆幅、低工作电压、低功耗、可拉伸有机器件的中等规模电路集成复杂性。我们的电子皮肤模仿生物感觉运动回路，当施加压力增加的刺激时，固态突触晶体管会引发更强的驱动。
