In healthcare applications, the remote monitoring of moving patients depends on wearable nodes that should be mobile. Thus, wearable nodes should be power mains-disconnected most of the time to enable natural wandering of patients in the area. Thus, easy-to-use models are utilized in a seamless way. From this perspective, it becomes necessary to develop a generation of wearable nodes that are energy self-sustainable with minimal dependency on fixed power sources and also more safe in light of world health organization recommendations. In this paper, a solar energy harvesting technique is proposed to provide a mains power supply for an independent continuous operation of a patient monitoring node in sunny environments. A case study is built experimentally whereas the proposed designed node is architected as a combined node that enables parallel measurements of heart rate, blood oxygen saturation (SpO2), and body temperature. The experimental results show that the wearable node can survive more than 28 h without battery recharging from the mains. While the charging time of the battery from the solar energy harvesting is approximately 2 h.

物联网医疗应用中的自持可穿戴传感器节点架构
在医疗保健应用中,对移动患者的远程监视取决于应该是可移动的可穿戴节点。因此,可穿戴节点在大多数情况下应断开电源,以使该区域的患者自然徘徊。因此,以无缝方式利用易于使用的模型。从这个角度出发,有必要开发一代可穿戴节点,这些节点可自我维持能源,并且对固定电源的依赖性最小,并且根据世界卫生组织的建议也更加安全。在本文中,提出了一种太阳能收集技术,可为阳光明媚的环境中患者监护节点的独立连续运行提供干线电源。2),体温。实验结果表明,该可穿戴节点无需电池从市电充电即可存活超过28小时。而从太阳能收集电池的充电时间约为2小时。
