Wearable Respiratory Data During Pulmonary Rehabilitation Exercises (Magnetic Field-Based and Piezoelectric-Based Wearables Against Airflow Transducer)

Dataset for validation of a new magnetic field-based wearable breathing sensor (MAG), which uses the movement of the chest wall as a surrogate measure of respiratory activity. Based on the principle of variation in magnetic field strength with the distance from the source, this system explores Hall effect sensing, paired with a permanent magnet, embedded in a chest strap.The proposed wearable device was evaluated using the gold-standard as a reference system - an airflow transducer - and compared to a commonly used wearable device with analogous usability but with a different working principle - a piezoelectric-based sensor (PZT) embedded in a chest strap.A total of 16 healthy participants (M/F parity) performed 15 different activities, representative of pulmonary rehabilitation exercises, simultaneously using the three devices. The dataset was created for evaluation of the proposed device based on detection of flow reversal events, as well as fiducials detection latency.The 15 activities executed by the participants were: standing normal breathing (STNB); seated normal breathing (SNB); seated guided-breathing (SGB); normal/deep-alternated breathing (MIXB); march (MCH); squat (SQT); adduction/abduction of the left/right arm (AAL/AAR); adduction/abduction of the left/right leg (ALL/ALR); upwards (overhead) left/right arm extension (UAL/UAR); shoulder elevation (SE); side stretch (SS); and seated trunk rotation (TR).

本数据集旨在验证一款新型基于磁场的人体穿戴式呼吸传感器（MAG）的有效性，该传感器以胸壁运动作为呼吸活动的替代性指标。该系统基于磁场强度随源距离变化的原理，探索了霍尔效应传感技术，并结合永久磁铁，嵌入于胸带之中。所提出的穿戴设备以金标准参照系统——气流传感器——进行评估，并与一款常用的人体穿戴设备进行比较，后者虽具有相似的易用性，但其工作原理不同——即胸带中嵌入的压电传感器（PZT）。共有16名健康参与者（男女性别比例）完成了15种不同的活动，这些活动代表肺康复锻炼，他们同时使用三种设备进行测试。该数据集的创建旨在评估所提出设备的性能，包括对流量反转事件的检测以及基准点检测的延迟。参与者执行的活动包括：站立正常呼吸（STNB）、坐姿正常呼吸（SNB）、坐姿引导呼吸（SGB）、正常/深交替呼吸（MIXB）、行军（MCH）、蹲下（SQT）、左右手臂的内收/外展（AAL/AAR）、左右腿的内收/外展（ALL/ALR）、向上（头顶）左右手臂伸展（UAL/UAR）、肩部抬高（SE）、侧伸展（SS）以及坐姿躯干旋转（TR）。
