Self-powered visualized sensor with skin-like functionality is highly anticipated for practical application in health monitoring, human-machine interaction, and robotics. However, the existing methods are disadvantaged by their poor performance in sensitivity and spatial fidelity due to the low pixel density, brightness, or conformability. Herein, a novel self-powered skin-inspired visualized sensor (SP-SIVS) is developed by means of triboelectrification-induced electroluminescence (TIEL) technique. By integrating surface and bulk charge generation with a high-voltage corona charging treatment, a significant improvement is achieved in the brightness (by 10-fold) and spatial resolution (100 µm) of the SP-SIVS. Meanwhile, Young's modulus (94 kPa) is maintained at a level comparable to human skin, with tensile strength and elongation exceeding 1000 kPa and 1000%, respectively. Furthermore, SP-SIVS is verified as applicable to serve such purposes as wearable motion detection, fingerprint morphology imaging, and information interaction. This work contributes an innovative framework to the development of SP-SIVS with high-brightness, high-resolution, and sustainability, laying a foundation for its popularization as a novel interactive medium required for advanced photonic applications.

用于光子成像和信息交互的高亮度和高分辨率摩擦带电诱导电致发光皮肤


具有类似皮肤功能的自供电可视化传感器在健康监测、人机交互和机器人技术中的实际应用备受期待。然而，由于像素密度、亮度或一致性低，现有方法在灵敏度和空间保真度方面的性能较差。在此，通过摩擦带电诱导电致发光 （TIEL） 技术开发了一种新型自供电类皮肤启发可视化传感器 （SP-SIVS）。通过将表面和体电荷生成与高压电晕充电处理相结合，SP-SIVS 的亮度（10 倍）和空间分辨率 （100 μm） 得到了显著提高。同时，杨氏模量 （94 kPa） 保持在与人体皮肤相当的水平，拉伸强度和伸长率分别超过 1000 kPa 和 1000%。此外，SP-SIVS 被验证可用于可穿戴运动检测、指纹形态成像和信息交互等用途。这项工作为具有高亮度、高分辨率和可持续性的 SP-SIVS 的发展提供了一个创新框架，为其作为高级光子应用所需的新型交互介质的普及奠定了基础。
