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：合作研究：该奖项由2009年美国复苏和再投资法案（公法111-5）资助。该研究的目标是推进惯性传感与远程RF询问技术的结合。这项工作将利用无线设备，惯性传感器和系统设计的发展，以实现一类新的无线传感器，在能源需求方面接近被动。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，以便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、顺应性更强和自增强的抗磁悬浮，以获得上级性能，同时实现基于窄带谐波再辐射的高效收发器。频率鉴别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。大部分的智力价值是致力于超灵敏和强大的惯性传感器的发展，高效率的近无源谐波耦合收发器的就业，以及一个新的无线遥测方法，允许在恶劣的信道条件下操作，利用窄带滤波和频率歧视的调查。因此，这项工作将实现嵌入式无线惯性传感的变革。该项目的成果将有利于无线传感器系统的设计，推进当前最先进的惯性传感技术，并产生全新的遥感方法。行业伙伴关系将使研究团队能够在学术界之外广泛传播成果。这两个机构的协同中心活动将受益于调查结果。该项目还将影响这两所大学的课程，同时利用正在进行的项目，吸引代表性不足的学生到工程。
