Given that wearable sensors that are attached on patients for the purpose of continuous real-time medical monitoring typically need to remain operational for periods of up to 24 hours before a battery change or recharge, power preservation schemes play a critical role in minimizing any possible disruption to a patient's daily activities. In this paper, we propose a motion-based wake-up scheme, a feature which combines motion detection with existing power preservation schemes in order to achieve a balance between energy saving and data timeliness, particularly in critical situations. As a showcase, we have integrated this feature with a healthcare application and demonstrate the capability of the scheme to deal with critical events, e.g., when a patient falls down from the bed. This showcase affirms the effective uses of our proposed motion-based wake-up scheme.
鉴于用于患者连续实时医疗监测的可穿戴传感器通常需要在更换电池或充电前持续运行长达24小时，节能方案对于最大限度减少对患者日常活动的任何可能干扰起着关键作用。在本文中，我们提出了一种基于运动的唤醒方案，该功能将运动检测与现有的节能方案相结合，以在节能和数据及时性之间取得平衡，特别是在危急情况下。作为一个展示，我们已将此功能集成到一个医疗保健应用程序中，并展示了该方案处理危急事件的能力，例如当患者从床上摔下时。这个展示证实了我们提出的基于运动的唤醒方案的有效用途。
