Advancements of virtual reality technology pave the way for developing wearable devices to enable somatosensory sensation, which can bring more comprehensive perception and feedback in the metaverse-based virtual society. Here, we propose augmented tactile-perception and haptic-feedback rings with multimodal sensing and feedback capabilities. This highly integrated ring consists of triboelectric and pyroelectric sensors for tactile and temperature perception, and vibrators and nichrome heaters for vibro- and thermo-haptic feedback. All these components integrated on the ring can be directly driven by a custom wireless platform of low power consumption for wearable/portable scenarios. With voltage integration processing, high-resolution continuous finger motion tracking is achieved via the triboelectric tactile sensor, which also contributes to superior performance in gesture/object recognition with artificial intelligence analysis. By fusing the multimodal sensing and feedback functions, an interactive metaverse platform with cross-space perception capability is successfully achieved, giving people a face-to-face like immersive virtual social experience.

虚拟现实技术的进步为开发可实现体感的可穿戴设备铺平了道路，这可以在基于元宇宙的虚拟社会中带来更全面的感知和反馈。在这里，我们提出了具有多模式传感和反馈能力的增强触觉感知和触觉反馈环。这种高度集成的环由用于触觉和温度感知的摩擦电和热释电传感器以及用于振动和热触觉反馈的振动器和镍铬合金加热器组成。所有这些集成在环上的组件都可以直接由定制的低功耗无线平台驱动，用于可穿戴/便携场景。通过电压积分处理，通过摩擦电触觉传感器实现高分辨率连续手指运动跟踪，这也有助于通过人工智能分析在手势/物体识别方面表现出卓越的性能。通过融合多模态感知和反馈功能，成功实现了具有跨空间感知能力的交互式虚拟世界平台，给人一种面对面的沉浸式虚拟社交体验。
