柔性传感器和无线电子器件的最新进展推动了轻质且符合人体工程学的可穿戴感测手套的发展。这种手套可以在混合现实（MR）环境中使用，以在与各种对象交互期间提供触觉能力。然而，没有先前的研究表明，在MR对象操作的物理用户交互的定量测量。在这里，我们报告了一个MR集成的软生物电子系统的手套，用于量化用户的捏任务的变化。我们使用纳米制造技术来制造柔性传感器，无线电路和可伸缩的互连器，这些互连器与可穿戴手套无缝集成。带有集成电容压力传感器的可穿戴生物传感手套评估用户如何直接和间接地与物体交互。直接模式描述用户在MR中直接触摸和操纵对象。相反，在间接模式中，对象位于远处并且经由窄光束触摸。虚拟对象测量参数包括质量、运动延迟、动态摩擦系数、角阻力系数和线性阻力系数。与人类受试者的实验结果表明，在直接操作模式的捏力和动态摩擦系数和质量参数之间的正，线性关系。总的来说，MR使能的可穿戴生物传感手套系统在检测各种康复应用和MR人机界面的物理交互和感觉反馈方面具有独特的优势。
Recent advances in flexible sensors and wireless electronics have driven the development of lightweight and ergonomic wearable sensing gloves. Such gloves can be employed in mixed reality (MR) environments to give haptic capabilities during interactions with various objects. However, no prior study shows a quantitative measurement of physical user interactions of object manipulation in MR. Here, we report an MR-integrated soft bioelectronic system on a glove for quantifying the changes in the user's pinching tasks. We use nanomanufacturing techniques to fabricate flexible sensors, wireless circuits, and stretchable interconnectors seamlessly integrated with a wearable glove. The wearable biosensing glove with an integrated capacitive pressure sensor evaluates how users interact directly and indirectly interact with objects. The direct mode describes a user's direct touching and manipulating objects in MR. In contrast, in the indirect mode, objects are located far away and touched via a narrow light beam. The virtual object measurement parameters include mass, movement latency, dynamic friction coefficient, angular drag coefficient, and linear drag coefficient. The experimental results with human subjects show positive, linear relationships between pinching force and dynamic friction coefficient and mass parameters during the direct manipulation mode. Collectively, the MR-enabled wearable biosensing glove system offers unique advantages in detecting physical interactions and sensory feedback for various rehabilitation applications and MR human-machine interfaces.
