GOALI: COLLABORATIVE RESEARCH: PASSIVE, DIAMAGNETIC INERTIAL SENSING INTEGRATED WITH HIGH-SENSITIVITY TELEMETRY This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5).The objective of this research is to advance inertial sensing in combination with remote RF interrogation technologies. This work will leverage developments in wireless devices, inertial sensors and system design to realize a new class of wireless sensors that are near-passive in energy needs. Synergistic design practices will be used to achieve sufficient activation/communication range and sensitivity in order to enable numerous embedded sensing applications. The approach is to employ less damped, more compliant, and self-reinforced diamagnetic levitation in inertial sensors to obtain superior performance while implementing high-efficiency transceivers based on narrowband harmonic re-radiation. The frequency discrimination and narrowband filtering avoids interference while enhancing the ability to detect lower power signals. Much of the intellectual merit is devoted to the development of ultra-sensitive and robust inertial sensors, the employment of high-efficiency near-passive harmonic-coupled transceivers, and the investigation of a new wireless telemetry methodology that permits operation under harsh channel conditions by capitalizing on narrowband filtering and frequency discrimination. As a result, this work will enable a transformative change in embedded wireless inertial sensing. The outcomes of the project will benefit wireless sensor system design, advance current state-of-the-art inertial sensing technology and yield fundamentally new approaches to remote sensing. The industry partnership will enable the research team to broadly disseminate results beyond the academic community. At both institutions there are synergistic center activities which will benefit from the results of the investigation. The project will also impact curriculum at both universities, while leveraging ongoing programs that attract underrepresented students to engineering.

目标：协作研究：被动抗磁惯性传感与高灵敏度遥测相结合 该奖项由 2009 年美国复苏和再投资法案（公法 111-5）资助。这项研究的目的是结合先进的惯性传感技术来推进惯性传感远程射频询问技术。这项工作将利用无线设备、惯性传感器和系统设计的发展来实现能源需求近乎被动的新型无线传感器。将使用协同设计实践来实现足够的激活/通信范围和灵敏度，以实现众多嵌入式传感应用。该方法是在惯性传感器中采用阻尼更小、更顺从的自增强抗磁悬浮，以获得卓越的性能，同时实现基于窄带谐波再辐射的高效收发器。鉴频和窄带滤波避免了干扰，同时增强了检测较低功率信号的能力。大部分智力成果致力于开发超灵敏和鲁棒的惯性传感器、使用高效近无源谐波耦合收发器以及研究一种新的无线遥测方法，该方法允许在恶劣的信道条件下运行利用窄带滤波和频率鉴别。因此，这项工作将使嵌入式无线惯性传感发生革命性的变化。该项目的成果将有利于无线传感器系统设计，推进当前最先进的惯性传感技术，并产生全新的遥感方法。行业合作伙伴关系将使研究团队能够在学术界之外广泛传播研究成果。两个机构都有协同中心活动，这些活动将从调查结果中受益。该项目还将影响两所大学的课程，同时利用正在进行的项目吸引代表性不足的学生进入工程学领域。
