AIR: Development and Evaluation of Self-Powered Piezo-Floating-Gate Sensor Chipsets for Embedded and Implantable Structural Health Monitoring

这项提议利用了美国国家科学基金会先前资助的工作，这些工作导致了一种自供电的压电式浮栅(PFG)无线传感器的专利。该传感器功率超低，能够存储应变数据，非常适合嵌入对安全至关重要的物理结构和基础设施中，以便在结构的整个生命周期内通过无线RFID读取器进行结构健康监测。拟议的工作将解决导致坚固的原型和随后的制造和商业化所需的技术差距，即开发所有支持的传感电路和无线接口电路和软件，展示PFG无线传感器的远程配置和询问。当通过拟议的工作将PFG无线传感器整合到原型系统中时，可能会对大类系统的健康监测和故障诊断产生重大影响，对于这些系统，此类监测系统必须是自主的、自给自足的、自行发电和零维护的。因此，民用基础设施、生物医学设备和系统、个人和民用交通以及能源等部门代表着潜在的市场。在这些部门使用的安全关键系统中采用这种嵌入式传感器元件，最终可以减少意外系统故障造成的伤亡。

This proposal leverages prior NSF funded work that resulted in the patent of a self-powered piezo-floating-gate (PFG) wireless sensor. The sensor is ultra low power and capable of storing strain data, making it highly suitable for embedding in safety-critical physical structures and infrastructure for structural health monitoring via wireless RFID readers over the lifetime of the structure. The proposed effort will address the technological gaps necessary to lead to a robust prototype and subsequent manufacture and commercialization, namely development of all supporting sensing circuitry and wireless interface circuitry and software, demonstrating remote configuration and interrogation of the PFG wireless sensor. The PFG wireless sensor when incorporated into a prototype system via the proposed work, has the potential to have significant impact in the health monitoring and fault diagnosis of large classes of systems for which such monitoring systems must be autonomous, self-contained, generate their own power and be zero-maintenance. As a result such sectors as civil infrastructure, biomedical devices and systems, individual and civil transportation, and energy represent potential markets. Adoption of such embedded sensor elements in the safety critical systems used in these sectors can ultimately result in fewer injuries and fatalities arising from unexpected system failures.
