项目摘要

The broader impact/commercial potential of this I-Corps project is to improve food and health product safety in the US. This can reduce the economic burden associated with disease and infection caused by bacteria on surfaces. The proposed technology can be used to determine adherence to cleaning protocols that are used to keep food and healthcare facilities safe. It can also be used to help monitor chronic wounds, thus reducing the number of clinical visits for routine status check-ups. The ability to conduct real time measurement of biofilms in a closed environment is currently unavailable in the market. This technology can potentially impact food safety and also health care markets.This I-Corps project will further develop a wireless sensor platform technology that is proposed for use in monitoring growth of biofilms or fluid build-up in closed systems such as bandages or on surfaces such as food preparation areas or healthcare counters. The sensor is a platform technology that consists of a flexible sensor, a reader, and algorithm to translate the wireless signal. The sensor is a planar, Archimedean coil that is an open circuit inductor capacitor that forms a resonant structure. It can be placed on or in surface materials or bandages. As cells or a biofilm grow on the surface of the resonator, this changes the local dielectric and a large shift in the resonant frequency is observed. This can be sampled wirelessly using a vector network analyzer.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

该 I-Corps 项目更广泛的影响/商业潜力是改善美国的食品和保健产品安全。这可以减少与表面细菌引起的疾病和感染相关的经济负担。所提出的技术可用于确定对用于保证食品和医疗设施安全的清洁协议的遵守情况。它还可用于帮助监测慢性伤口，从而减少常规状态检查的临床就诊次数。目前市场上尚不具备在封闭环境中对生物膜进行实时测量的能力。这项技术可能会影响食品安全以及医疗保健市场。该 I-Corps 项目将进一步开发一种无线传感器平台技术，该技术拟用于监测绷带等封闭系统中或食品准备区或医疗柜台等表面上的生物膜生长或液体积聚。该传感器是一种平台技术，由灵活的传感器、读取器和转换无线信号的算法组成。该传感器是一个平面阿基米德线圈，它是一个形成谐振结构的开路电感电容器。它可以放置在表面材料或绷带之上或之中。当细胞或生物膜在谐振器表面生长时，局部电介质会发生变化，并且会观察到谐振频率的大幅变化。这可以使用矢量网络分析仪进行无线采样。该奖项反映了 NSF 的法定使命，并且通过使用基金会的智力优点和更广泛的影响审查标准进行评估，被认为值得支持。
