With advances in mobile computing and virtual/augmented reality technologies, communicating through touch using wearable haptic devices is poised to enrich and augment current information delivery channels that typically rely on sight and hearing. To realize a wearable haptic device capable of effective data communication, both ergonomics and haptic performance (i.e., array size, bandwidth, and perception accuracy) are essential considerations. However, these goals often involve challenging and conflicting requirements. We present an integrated approach to address these conflicts, which includes incorporating multilayered dielectric elastomer actuators, a lumped-parameter model of the skin, and a wearable frame in the design loop. An antagonistic arrangement—consisting of an actuator deforming the skin—was used to achieve effective force transmission while maintaining a low profile, and the effect of the wearable frame and structure was investigated through lumped-model analysis and human perception studies.

可穿戴纺织品嵌入式介电弹性体致动器触觉显示器

随着移动计算和虚拟/增强现实技术的进步，使用可穿戴触觉设备通过触摸进行通信有望丰富和增强通常依赖视觉和听觉的当前信息传递渠道。为了实现能够进行有效数据通信的可穿戴触觉设备，人体工程学和触觉性能（即阵列大小、带宽和感知精度）都是必不可少的考虑因素。然而，这些目标通常涉及具有挑战性和相互冲突的要求。我们提出了一种解决这些冲突的综合方法，其中包括在设计循环中结合多层介电弹性体致动器、皮肤的集中参数模型和可穿戴框架。
