受皮肤启发的传感电子器件优选地是可拉伸的和可自我修复的，以满足长时间佩戴的需求。在这里，我们报道了一种用于生物启发电子皮肤的内在可拉伸和自修复的摩擦电子晶体管，其中输出电流可以通过外部接触通电来调制。通过动态非共价交联和聚合物链的自结合，该器件可以拉伸到50%超过500次循环而没有显著的性能损失，并且在多次完整切割循环后在室温下恢复，具有高愈合效率（>99%）。此外，该设备具有高皮肤兼容性，用于多功能感测，例如检测接触和接近。最后，一个bioinspired电子皮肤变形/损坏下运行的机器人控制和抓取对象。这项工作不仅为人类和机器人皮肤提供了仿生摩擦电子晶体管，而且在可穿戴电子学，机器人学和仿生学中展示了未来强大的摩擦电子学的广阔前景。这项工作展示了一种主动的生物感应机制，可以在环境和传感器之间进行交互。·该器件可以重复拉伸超过500个循环，最高可达50%的应变。·器件性能可在室温下恢复，最大愈合效率超过99%。·该设备具有高皮肤兼容性，用于多功能感测，例如检测接触和接近。
Skin inspired sensory electronics are preferable to be stretchable and self-healable to satisfy the prolonged wearing demands. Here, we reported an intrinsically stretchable and self-healable tribotronic transistor for bioinspired e-skin, in which the output current can be modulated by external contact electrification. By dynamic non-covalent crosslinking and self-bonding of polymer chains, the device can be stretched to 50% for more than 500 cycles without significant performances loss, and restored at room temperature after multiple cycles of a complete cut with high healing efficiency (>99%). Moreover, the device has high skin compatibility for multifunctional sensing, such as detection of contact and proximity. Finally, a bioinspired e-skin operating under deformations/damages is demonstrated for robot control and grasping objects. This work has not only presented a biomimetic tribotronic transistor for human and robot skins, but also exhibited broad prospects for future robust tribotronics in wearable electronics, robotics, and bionics. • This work demonstrates an active bioinspired sensing mechanism that can interact between the ambient and sensors. • The device can be repeatedly stretched for more than 500 cycles of up to 50% strain. • The device properties can be restored at room temperature, with more than 99% maximum healing efficiency. • The device has high skin compatibility for multifunctional sensing, such as detection of contact and proximity.
