Mass-Sensitive Microsensor Platform for Liquid-Phase Environmental Sensing

该项目旨在开发一种质量敏感的化学传感器平台，用于检测水中挥发性有机化合物（VOCs）。所使用的技术将采用化学敏感富集层，它可以选择性地吸收质量并改变传感器设备的共振频率。谐振腔的形状是一种新颖的圆盘状谐振腔，而不是悬臂谐振腔。这项创新是通过剪切而不是压缩周围流体来提高频率分辨率。所提出的传感器具有包含在各种紧凑的化学和生物传感系统中的潜力，并且可能作为分布式网络的一部分实施。这种系统的成功开发可能对健康和安全都有好处。

0606981BrandThe project seeks to develop a mass-sensitive chemical sensor platform for detection of volatile organic compounds (VOCs) in water. The technology to be used would employ chemically sensitive enrichment layers which sorb mass selectively and change the resonance frequency of the sensor device. The shape of the resonator is a novel disk-shaped rather than a cantilever resonator. This innovation is to improve the frequency resolution by employing shear, rather than compression of the surrounding fluid. The proposed sensor has the potential for inclusion in a wide variety of compact chemical and biological sensing systems, and possible implementation as part of a distributed network. The successful development of a system of this kind would potentially have both health and security benefits.
