Wearable Photoelectrocatalytic Personal Environmental Exposure Monitor

描述（由申请人提供） 传统的环境暴露监测需要庞大的仪器，而不能提供个性化的环境暴露历史。Valencell的长期目标是提供一种非侵入性、低姿态、实时、经济实惠的个人环境暴露监测平台，用户几乎不会注意到该平台，以获得最大的性能和便利性。该平台将提供一个定量的，可靠的，现场测量的个人水平，接触点接触到各种空气传播的化学毒素的特别关注的健康意识的最终用户，体育爱好者，免疫功能低下，和医疗专业人员。集成的蓝牙通信协议将用于向手机或PDA无线发送实时信息。进而，该信息然后可以无线地发送到在线数据库，用于存储和处理与个人健康、个人环境因素和用户人口统计相关的信息。 该第一阶段可行性研究的具体目标是开发一种新型传感器元件，该传感器元件可在同一紧凑型设备中灵活监测挥发性有机化合物（VOC）、臭氧、一氧化碳、多环芳烃（PAH）和其他空气中的活性物质。灯丝加热氧化锡VOC传感器，固态VOC传感的主力，是足够紧凑，但需要显着的操作功率，缺乏蒸汽特异性。Valencell的创新方法是开发一种新型宽带隙（WBG）VOC传感器，与标准金属氧化物传感器相比，该传感器具有更强的蒸汽特异性和更低的功耗。这一创新使开发一种新型、低功耗（<10 mW）、实时（<100 ms采样）、紧凑（< 10 cm3）、可穿戴的VOC监测仪成为可能，该监测仪能够长期使用电池供电，具有高特异性和宽灵敏度（0.1至1000 ppm）。 在这项计划中，Valencell将利用北卡罗来纳州州立大学（NCSU）沉积的新型WBG金属氧化物薄膜制造传感器电极。这些传感器电极的功能将通过在钟罩VOC测试台中评估每个电极的灵敏度和特异性来验证。然后将传感器电极集成到独立的VOC传感器原型中，以便在VOC测试台中对预测的性能规格进行统计验证。

DESCRIPTION (provided by applicant) Conventional environmental exposure monitoring requires bulky instrumentation without providing a personalized history of environmental exposure. Valencell's long-term goal is to provide a noninvasive, low-profile, real-time, affordable personal environmental exposure monitor platform that is virtually unnoticed by the user for maximum performance and convenience. This platform will provide a quantitative, reliable, in-field measurement of personal-level, point-of-contact exposure to a variety of airborne chemical toxins of particular interest to health conscious end-users, sports enthusiasts, the immunocompromised, and medical professionals. Integrated Bluetooth communication protocols will be employed towards sending real-time information wirelessly to a cell phone or PDA. In turn, this information can then be sent wirelessly to online databases for storing and processing information relating personal health with personal environmental factors and user demographics. The specific goal of this Phase I feasibility study is the development of a novel sensor element providing the flexibility of monitoring volatile organic compounds (VOCs), ozone, carbon monoxide, polycyclic aromatic hydrocarbons (PAHs), and other reactive airborne species in the same compact device. Filament-heated tin oxide VOC sensors, the workhorse of solid-state VOC sensing, are sufficiently compact but require significant operating power and lack vapor specificity. Valencell's innovative approach is the development of a novel wide band gap (WBG) VOC sensor offering enhanced vapor specificity and dramatically reduced power consumption over standard metal oxide sensors. This innovation enables the development of a novel, low-power (<10 mW), real-time (<100 ms sampling), compact (< 10 cm3), wearable VOC monitor capable of long-term battery-powered operation, high specificity, and broad sensitivity (0.1 to 1000 ppm). In this program, Valencell will fabricate sensor electrodes from novel WBG metal-oxide films deposited by North Carolina State University (NCSU). The functionality of these sensor electrodes will then be validated by evaluating the sensitivity and specificity of each electrode in a bell jar VOC test bed. The sensor electrodes will then be integrated into a self-contained VOC sensor prototype such that the predicted performance specifications can be statistically validated in the VOC test bed.
