GOALI - Wireless Life Monitoring Transponders

集成、混合和复杂的系统夏威夷大学的Victor M.Lubecke GOALI：用于生命监测的无线电应答器智能优点：多普勒雷达和射频识别(RFID)都涉及调制后向散射技术。该项目将这些技术结合在一起，以超越这两种技术的人类生命体征监测能力。这将通过两种不同的多普勒雷达应用无源射频(RF)反向散射标签来实现。首先，提出了身体佩戴的“创可贴”应答器标签，以在时间和频率上修改多普勒雷达返回信号，将受试者的心肺运动与其他运动和受试者隔离开来，同时促进对额外生物医学数据的传感和遥测。将这些无线标签与多普勒运动传感相结合，可以检测和隔离标记对象中的未标记对象。第二，建议将后向散射标签作为环境分布的“雷达节点”应答器，这将形成一个双基地雷达系统，以抑制发射机相位和“抖动”噪声效应，以实现远距离的心肺运动传感，同时还允许通过利用环境中已有的射频信号进行被动传感。对其他生物医学参数(如体温)敏感的射频标签电路组件的设计和制造，以及标签电路的制造和一次性传感器的封装也将进行调查。广泛影响：该项目的成果可以在医疗保健、应急响应和军事应用领域产生有益于社会的有价值的工具。这项研究还将提供一个特别鼓舞人心的教育机会，利用夏威夷对远程医疗工具的独特需求，接触到多样化的少数民族学生群体，这些学生传统上没有得到当地教育和工业机会的服务。这项研究计划将特别有利于参与涉及生物传感器和无线遥测的跨学科研究的研究生和本科生。该项目的一个重要方面将是夏威夷大学马诺阿分校的学生与行业联合首席研究员的互动，包括在行业合作伙伴处延长培训时间。

Integrative, Hybrid and Complex SystemsVictor M. LubeckeUniversity of HawaiiGOALI: Radio Transponders for Life MonitoringIntellectual Merit: Both Doppler radar and radio frequency identification (RFID) involve modulated backscatter technology. This project combines these technologies to transcend the human life sign monitoring capabilities of both technologies. This will be achieved through two different Doppler radar applications of passive radio frequency (RF) backscatter tags. First, body worn "band-aid" transponder tags are proposed to modify Doppler radar return signals in time and frequency to isolate a subject's cardiopulmonary motion from other motion and subjects, while facilitating the sensing and telemetry of additional biomedical data. Combining these wireless tags with Doppler motion sensing allows detection and isolation of untagged subjects among tagged subjects. Second, backscatter tags as environmentally distributed "radar node" transponders are proposed, which would form a bi-static radar system to suppress transmitter phase and "shake" noise effects to enable cardiopulmonary motion sensing at large distances, while also allowing passive sensing by exploiting RF signals already present in the environment. The design and fabrication of RF tag circuit components that are sensitive to additional biomedical parameters such as body temperature, will also be investigated along with tag circuit fabrication, and packaging for disposable sensors.Broader Impact: The outcomes of this project can lead to valuable tools beneficial for society in the areas of healthcare, emergency response, and military applications. The research would, also, present a particularly motivating educational opportunity that leverages Hawaii's unique needs for remote healthcare tools, and reaches out to a diverse population of ethnic minority students that have been traditionally underserved by local educational and industrial opportunities. This research program would particularly benefit the graduate and undergraduate students participating in interdisciplinary research involving biosensors and wireless telemetry. An important aspect of this program will be the interactions of University of Hawaii at Manoa students with the industrial co-principal investigator, including extended periods of training at the industry partner.
