This Small Business Innovation Research (SBIR) Phase I research project will demonstrate that innovative MEMS (Micro-Electro-Mechanical Systems) sensor systems can be fabricated to enable on-chip parallel measurements of true viscosity values at various shear rates for liquids essential in food processing. Current instruments that measure the true viscosity are slow, expensive and are not portable. Hence for process control or quality control applications, portable sensors that are only capable of apparent viscosity measurements are often used. The proposed novel micro-scale sensor system will be portable and will enable simultaneous true viscosity value measurements at various shear rates, thereby increasing sensor response time and cost-effectiveness. This research will address key technical challenges in fabrication of the micron length scale sensor system. In Phase I, proof-of-concept of the innovative viscosity sensor will be demonstrated using standard viscoelastic liquids. If successful the proposed innovative viscosity sensor system will allow rapid measurements of true viscosity values enabling efficient and accurate process control. The viscosity sensor system will be a next generation instrument offering more features in a compact size. This research effort will also increase scientific understanding of viscoelastic flows in micron-size channels that may inspire additional efforts and interdisciplinary collaborations among researchers.

这个小型企业创新研究（SBIR）第一阶段研究项目将证明，可以制造创新的MEMS（微机电系统）传感器系统，以实现在食品加工中必不可少的液体在各种剪切速率下的真实粘度值的片上并行测量。目前测量真实粘度的仪器速度慢、价格昂贵且不便携。因此，对于过程控制或质量控制应用，通常使用仅能够进行表观粘度测量的便携式传感器。所提出的新型微尺度传感器系统将是便携式的，并且将能够在各种剪切速率下同时进行真实粘度值测量，从而增加传感器响应时间和成本效益。这项研究将解决关键技术的挑战，在微米尺度传感器系统的制造。在第一阶段，将使用标准粘弹液体对创新粘度传感器的概念验证进行演示。如果成功的话，所提出的创新粘度传感器系统将允许快速测量真实粘度值，从而实现有效和准确的过程控制。粘度传感器系统将是下一代仪器，在紧凑的尺寸中提供更多功能。这项研究工作还将增加对微米尺寸通道中粘弹性流动的科学理解，这可能会激发研究人员之间的额外努力和跨学科合作。
