Tactility bridges humans and the external world. Although human skin's tactile receptors provide comprehensive perception, developing a biomimetic tactile system with both dynamic and static functions and rapid conversion remains a challenge. Here, we report a switchable dynamic-static tactile system. It features a rapid 1-millisecond transition between dynamic and static modes via light modulation, an all-in-one structure for simplicity and practicality, a remarkable balance of high sensitivity (198.45 per kilopascal) and wide pressure range (0.0137 to 207 kilopascals), a tunable sensitivity, and a sensing-feedback closed loop. The dynamic mode responds to vibrations, and the static mode responds to static pressure and superposition. In various real-world potential scenarios such as object detection and perception under vibration interference and human-computer interaction, it shows excellent performance. A closed-loop system with feedback and deep learning achieves user-encrypted Morse code haptic secret communication, paving the way for advancements in intelligence and virtual/augmented reality.
触觉连接着人类与外部世界。尽管人类皮肤的触觉感受器能提供全面的感知，但开发一种兼具动态和静态功能且能快速转换的仿生触觉系统仍是一项挑战。在此，我们报道了一种可切换的动态-静态触觉系统。它具有通过光调制在动态和静态模式之间快速实现1毫秒转换的特性，采用一体化结构以实现简单性和实用性，在高灵敏度（每千帕198.45）和宽压力范围（0.0137至207千帕）之间实现了显著平衡，具有可调灵敏度以及传感-反馈闭环。动态模式响应振动，静态模式响应静态压力和叠加。在诸如振动干扰下的物体检测与感知以及人机交互等各种现实世界潜在场景中，它展现出卓越性能。一个具有反馈和深度学习的闭环系统实现了用户加密的摩尔斯电码触觉秘密通信，为智能以及虚拟/增强现实的进步铺平了道路。
