Abstract

Wearable human-machine interface (HMI) with bidirectional and multimodal tactile information exchange is of paramount importance in teleoperation by providing more intuitive data interpretation and delivery of tactilely related signals. However, the current sensing and feedback devices still lack enough integration and modalities. Here, we present a Tactile Sensing and Rendering Patch (TSRP) that is made of a customized expandable array which consists of a piezoelectric sensing and feedback unit fused with an elastomeric triboelectric multidimensional sensor and its inner pneumatic feedback structure. The primary functional unit of TSRP is mainly featured with a soft silicone substrate with compact multilayer structure integrating static and dynamic multidimensional tactile sensing capabilities, which synergistically leverage both triboelectric and piezoelectric effects. Additionally, based on the air chamber created by the triboelectric sensor and the converse piezoelectric effect, it provides pneumatic and vibrational haptic feedback simultaneously for both static and dynamic perception regeneration. With the aid of the other variants of this unit, the array shaped TSRP is capable of simulating different terrains, geometries, sliding, collisions, and other critical interactive events during teleoperation via skin perception. Moreover, immediate manipulation can be done on TSRP through the tactile sensors. The preliminary demonstration of TSRP interface with a completed control module in robotic teleoperation is provided, which shows the feasibility of assisting certain tasks in a complex environment by direct tactile communication. The proposed device offers a potential method of enabling bidirectional tactile communication with enriched key information for improving interaction efficiency in the fields of robot teleoperation and training.

摘要

具有双向和多模态触觉信息交换功能的可穿戴人机界面(HMI)在远程操作中至关重要,它能提供更直观的数据解读并传递触觉相关信号。然而,当前的传感和反馈设备仍缺乏足够的集成度和模态。在此,我们展示了一种触觉传感与渲染贴片(TSRP),它由定制的可扩展阵列制成,该阵列由一个压电传感与反馈单元、一个与弹性体摩擦电多维传感器及其内部气动反馈结构融合而成。TSRP的主要功能单元主要特点是具有柔软的硅树脂基板,其紧凑的多层结构集成了静态和动态多维触觉传感能力,协同利用了摩擦电效应和压电效应。此外,基于摩擦电传感器产生的气室和逆压电效应,它能同时为静态和动态感知再生提供气动和振动触觉反馈。借助该单元的其他变体,阵列形状的TSRP能够通过皮肤感知模拟远程操作过程中的不同地形、几何形状、滑动、碰撞及其他关键交互事件。此外,通过触觉传感器可直接在TSRP上进行即时操作。文中给出了TSRP界面与机器人远程操作中完整控制模块的初步演示,展示了通过直接触觉通信在复杂环境中协助完成某些任务的可行性。所提出的设备提供了一种潜在方法,可实现具有丰富关键信息的双向触觉通信,以提高机器人远程操作和训练领域的交互效率。
