Ultrasonic wireless data for extremely low-power wake-up receivers

这项研究的目标是开发极低功耗的唤醒接收器。该方法是使用新的超声波数据通信设备和电子设备。在用于环境智能、结构和资产监控以及个人健康监控的无线传感器和标签网络中，传感标签使用唤醒接收器来监控来自中央控制节点的信息请求。这些始终在线的设备需要以极低的功率运行，以节省电池寿命或利用从环境中收集的能量进行运行。与目前基于无线电通信的解决方案相比，建议的超声波数据通信技术提供了两个数量级的功率降低。一种结合了柔性聚合物压电体和集成电路的新型技术平台将使微型超声换能器成为可能。这些进展还可以通过各种媒体在接近感测、测距和通信方面取得重大进展，这些媒体应用于自动化、环境情报以及医疗诊断和健康监测，在这些领域，无线电传输较差或干扰不可接受。传感器和标签网络的使用仍处于初级阶段，拟议的研究和教育计划将提供新技术和人力资本，以应用这些技术造福社会。这一跨学科项目的研究生和本科生教育以及推广活动有助于培训超低功耗电子、设备微制造和集成以及传感器网络方面的下一代研究人员。超声波通信和本地化模块将与哈莱姆机器人联盟(Harlem Robotics League)共同开发，这是一个针对哈莱姆区少数族裔群体的公立高中生的社区外联计划。

The objective of this research is to develop extremely low-power wake-up receivers. The approach is using novel ultrasonic data-communication devices and electronics. In wireless sensor and tag networks for ambient intelligence, structural and asset monitoring and personal health monitoring, sensing tags employ wake-up receivers to monitor requests for information from the central control node. These always-ON devices need to operate with extremely low power to save battery life or enable operation from energy scavenged from the environment. The proposed ultrasonic data communication technologies offer two orders of magnitude of power reduction over current radio communication-based solutions. A novel technology platform combining flexible polymer piezoelectrics and integrated circuits will enable miniature ultrasonic transducers. These advances can also enable significant advances in proximity sensing, ranging, and communications through a variety of media with applications in automation, ambient intelligence and medical diagnostics and health monitoring, where radio transmission is poor or interference is not acceptable. The use of sensor and tagging networks is still in its infancy and the proposed research and education program will offer new technology and human capital to apply these technologies for the benefit of society. The graduate and undergraduate education and outreach activities of this cross-disciplinary program help train the next generation of researchers in ultra-low power electronics, device microfabrication and integration, and sensor networks. Ultrasound communication and localization modules will be developed with the Harlem Robotics League, a community outreach program for public high school students from underrepresented minority groups in Harlem.
