Abstract:
Continuous monitoring of physiological signals from the human body is critical in health monitoring, disease diagnosis, and therapeutics. Despite the needs, the existing wearable medical devices rely on either bulky wired systems or battery-powered devices needing frequent recharging. Here, we introduce a wearable, self-powered, thermoelectric flexible system architecture for wireless portable monitoring of physiological signals without recharging batteries. This system harvests an exceptionally high open circuit voltage of 175-180 mV from the human body, powering the wireless wearable bioelectronics to detect electrophysiological signals on the skin continuously. The thermoelectric system shows long-term stability in performance for 7 days with stable power management. Integrating screen printing, laser micromachining, and soft packaging technologies enables a multilayered, soft, wearable device to be mounted on any body part. The demonstration of the self-sustainable wearable system for detecting electromyograms and electrocardiograms captures the potential of the platform technology to offer various opportunities for continuous monitoring of biosignals, remote health monitoring, and automated disease diagnosis.
摘要:
对来自人体的生理信号进行持续监测对于健康监测至关重要,疾病诊断,和治疗学。尽管需要,现有的可穿戴医疗设备依赖于笨重的有线系统或需要频繁充电的电池供电的设备。这里,我们介绍一种可穿戴的,自供电,热电灵活的系统架构,用于无线便携式监测生理信号,而无需对电池充电。该系统从人体获得175-180mV的异常高的开路电压,为无线可穿戴生物电子供电,以连续检测皮肤上的电生理信号。热电系统在稳定的电源管理下显示出7天的长期性能稳定性。集成丝网印刷,激光微加工,和软包装技术使多层,软,可穿戴设备安装在任何身体部位。用于检测肌电图和心电图的自我可持续可穿戴系统的演示抓住了平台技术的潜力,为连续监测生物信号提供了各种机会,远程健康监测,和自动疾病诊断。
