This Small Business Technology Transfer (STTR) Phase I research project will develop novel light weight, compact, non-contact electric field sensors for biomedical monitoring of low level signals. The sensors will utilize surface plasmon resonator structures fabricated on electro-optic materials such as lithium niobate. A single sensor will have a spatial resolution of a few microns, approaching the size of individual neurons, compared to the minimum several millimeters of existing contact sensors. Sensors can be interrogated using optical fibers for invasive research on brain activity, or grouped in arrays for clinical Electro-Encephalography (EEG) monitoring. This research will demonstrate the principle using a combination of fundamental modeling, test structure fabrication, and optical characterization with laboratory controlled electric fields. The proposed effort to make non-contact electric field sensors will provide a significant advancement in the state of the art in terms of sensitivity and spatial resolution. This would have an impact on brain research. The ease of use of non-contact sensors combined with the patient mobility provided by a wireless data link will make the package attractive for routine clinical brain monitoring.

这项小型企业技术转移(STTR)第一阶段研究项目将开发重量轻、紧凑、非接触式的新型电场传感器，用于低电平信号的生物医学监测。传感器将利用表面等离子激元谐振器结构，这种结构制造在电光材料上，如铌酸锂。单个传感器的空间分辨率将达到几微米，接近单个神经元的大小，而现有接触式传感器的最小空间分辨率为几毫米。可以使用光纤对传感器进行询问，以便对大脑活动进行侵入性研究，或者将传感器组合在阵列中进行临床脑电(EEG)监测。这项研究将使用基本建模、测试结构制造和光学表征与实验室控制的电场相结合的方法来演示这一原理。提出的制造非接触式电场传感器的努力将在灵敏度和空间分辨率方面提供最先进的技术。这将对大脑研究产生影响。非接触式传感器的易用性与无线数据链路提供的患者移动性相结合，将使该套装对常规临床大脑监测具有吸引力。
