活动和体力活动通常是通过间接量热法使用代谢率来估计的，以捕捉呼吸信息。体力劳动代表了用于优化可穿戴机器人系统的工作难度。因此，个性化和快速优化工作至关重要。虽然呼吸测量是估计新陈代谢成本的黄金标准，但这种方法需要一个笨重、笨重和僵硬的系统，限制了该系统的现场部署。在这里，本文报告了一个柔软、灵活的生物电子系统，它集成了一个可穿戴的脚踝-脚外骨骼，用于估计新陈代谢成本和体力，展示了基于生物反馈的实时可穿戴机器人调整的潜力。来自一系列活动的数据，包括步行、跑步和蹲着Biopatch和外骨骼，确定了代谢成本和心率变异性连续差异均方根(HRV-RMSSD)之间的关系(R=-0.758)。总体而言，集成外骨骼的可穿戴系统显示出开发一种可现场部署的外骨骼平台的潜力，该平台可以测量无线实时生理信号。
Activities and physical effort have been commonly estimated using a metabolic rate through indirect calorimetry to capture breath information. The physical effort represents the work hardness used to optimize wearable robotic systems. Thus, personalization and rapid optimization of the effort are critical. Although respirometry is the gold standard for estimating metabolic costs, this method requires a heavy, bulky, and rigid system, limiting the system's field deployability. Here, this paper reports a soft, flexible bioelectronic system that integrates a wearable ankle-foot exoskeleton, used to estimate metabolic costs and physical effort, demonstrating the potential for real-time wearable robot adjustments based on biofeedback. Data from a set of activities, including walking, running, and squatting with the biopatch and exoskeleton, determines the relationship between metabolic costs and heart rate variability root mean square of successive differences (HRV-RMSSD) (R = -0.758). Collectively, the exoskeleton-integrated wearable system shows potential to develop a field-deployable exoskeleton platform that can measure wireless real-time physiological signals.
