Wearable tactile interfaces can enhance immersive experiences in virtual/augmented reality systems by adding tactile stimulation to the skin along with the visual and auditory information delivered to the user. We introduce a flat cone dielectric elastomer actuator (FCDEA) array that is thin, soft, and capable of producing spatiotemporally adjustable and large static-to-dynamic force in response to electric voltage signals on large areas of the skin. Integration of the FCDEA array into a photomicrosensor array enables the implementation of a wearable wireless communication haptic patch. We demonstrate that the developed haptic patch allows users to communicate tactile information in real time while maintaining conformal contact with the skin. The haptic patch can also express the topology of 3D structures and render textures of virtual objects in response to localized vibration of the FCDEA array. We expect that the developed haptic patch will provide an immersive touching experience in virtual reality and facilitate tactile communication between users in various applications.
可穿戴触觉接口可以通过在向用户传递视觉和听觉信息的同时，向皮肤添加触觉刺激，来增强虚拟/增强现实系统中的沉浸式体验。我们介绍了一种扁平圆锥介电弹性体致动器（FCDEA）阵列，它很薄、很柔软，并且能够响应大面积皮肤上的电压信号，产生时空可调的大静态到动态力。将FCDEA阵列集成到光电微传感器阵列中，能够实现可穿戴无线通信触觉贴片。我们证明，所开发的触觉贴片允许用户实时传达触觉信息，同时与皮肤保持贴合接触。该触觉贴片还可以响应FCDEA阵列的局部振动，表达三维结构的拓扑结构并呈现虚拟物体的纹理。我们预计，所开发的触觉贴片将在虚拟现实中提供沉浸式触摸体验，并促进各种应用中用户之间的触觉通信。
