Abstract

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.

一种用于增强触觉秘密通信的可切换动静态触觉系统。

触觉是人类和外部世界的桥梁。虽然人体皮肤的触觉感受器提供了全面的感知能力，但开发具有动态和静态功能并能快速转换的仿生触觉系统仍然是一个挑战。在这里，我们报告了一个可切换的动态-静态触觉系统。它的特点是通过光调制在动态模式和静态模式之间快速转换1毫秒，简单实用的一体化结构，高灵敏度（198.45 /千帕斯卡）和宽压力范围（0.0137至207千帕斯卡）的显着平衡，可调灵敏度和传感反馈闭环。动态模式响应振动，静态模式响应静压和叠加。在振动干扰下的物体检测与感知、人机交互等多种现实潜在场景中，均表现出优异的性能。具有反馈和深度学习的闭环系统实现了用户加密的莫尔斯电码触觉秘密通信，为智能和虚拟/增强现实的进步铺平了道路。
