In the realm of virtual reality (VR), haptic feedback is integral to enhance the immersive experience; yet, existing wearable devices predominantly rely on skin contact feedback, lacking options for compact and non-contact breeze-sense feedback. Herein, we propose a compact and non-contact working model piezoelectret actuator for providing a gentle and safe breeze sensation. This easy-fabricated and flexible breeze-sense generator with thickness around 1 mm generates air flow pressure up to ~ 163 Pa, which is significantly sensed by human skin. In a typical demonstration, the breeze-sense generators array showcases its versatility by employing multiple coded modes for non-contact information transmitting. The thin thinness and good flexibility facilitate seamless integration with wearable VR setups, and the wearable arrays empower volunteers to precisely perceive the continuous and sudden breeze senses in the virtual environments. This work is expected to inspire developing new haptic feedback devices that play pivotal roles in human-machine interfaces for VR applications.
在虚拟现实（VR）领域，触觉反馈对于增强沉浸感至关重要；然而，现有的可穿戴设备主要依赖皮肤接触反馈，缺乏紧凑且非接触式微风感反馈的选项。在此，我们提出一种紧凑且非接触式工作模式的驻极体压电致动器，用于提供轻柔且安全的微风感。这种易于制造且灵活的微风感发生器厚度约为1毫米，可产生高达约163帕的气流压力，人体皮肤能明显感知到。在一个典型演示中，微风感发生器阵列通过采用多种编码模式进行非接触式信息传输，展示了其多功能性。其薄型和良好的柔韧性便于与可穿戴VR装置无缝集成，可穿戴阵列使志愿者能够在虚拟环境中精确感知连续和突然的微风感。这项工作有望激发开发新型触觉反馈设备，这些设备在VR应用的人机界面中发挥关键作用。
