GOALI - Wireless Life Monitoring Transponders

集成、混合和复杂系统夏威夷卢贝克大学GOALI：无线电应答器用于生命安全智能优点：多普勒雷达和射频识别（RFID）都涉及调制后向散射技术。 该项目结合了这些技术，超越了这两种技术的人类生命体征监测能力。 这将通过被动射频（RF）反向散射标签的两种不同的多普勒雷达应用来实现。 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，从而将受试者的心肺运动与其他运动和受试者隔离，同时促进附加生物医学数据的感测和遥测。 将这些无线标签与多普勒运动感测相结合允许在标记的对象中检测和隔离未标记的对象。 其次，提出了作为环境分布的“雷达节点”应答器的反向散射标签，其将形成双基地雷达系统以抑制发射器相位和“抖动”噪声效应，从而实现大距离处的心肺运动感测，同时还允许通过利用环境中已经存在的RF信号进行被动感测。 射频标签电路元件的设计和制造是敏感的额外的生物医学参数，如体温，也将被研究沿着与标签电路制造，包装一次性传感器。更广泛的影响：该项目的成果可以导致有价值的工具，有利于社会在医疗保健，应急响应和军事应用领域。 这项研究还将提供一个特别激励人心的教育机会，利用夏威夷对远程医疗工具的独特需求，并接触到传统上受当地教育和工业机会服务不足的少数民族学生的多样化人群。 这项研究计划将特别有利于研究生和本科生参与涉及生物传感器和无线遥测的跨学科研究。 该计划的一个重要方面将是夏威夷大学马诺阿分校学生与工业联合首席研究员的互动，包括在工业合作伙伴的长期培训。

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.
