This Small Business Innovation Research (SBIR) Phase II project will demonstrate prototypes of a new class of very broad band, wide dynamic range seismometers using magnetohydrodynamic (MHD) feedback and spectrum translation. The new instruments will be based on proven molecular electronic technology (MET), with force balancing feedback provided by the MHD effect on the electrolyte, which serves as the inertial mass. Radical noise reduction will be achieved via the use of signal modulation to produce spectrum translation. The goal is an instrument equal in performance to the best extant seismometers, while retaining the other desirable features of MET seismic sensors: low cost, low power, ruggedness, and manufacturability in volume production. These seismometers are expected to compete in all applications currently employing top-of-the-line traditional seismometers. Generally, this means scientific studies and monitoring in earthquake seismology. They will also be used in large sensor network applications, where ruggedness and small size and weight make them particularly attractive in boreholes and on the ocean bottom.

这个小型企业创新研究（SBIR）第二阶段项目将展示一种新型的超宽带、宽动态范围地震仪的原型，这种地震仪使用磁流体动力学（MHD）反馈和频谱转换。 新仪器将基于成熟的分子电子技术（MET），通过MHD效应对电解质（作为惯性质量）提供力平衡反馈。 通过使用信号调制来产生频谱平移，将实现彻底的降噪。 我们的目标是一种性能与现存最好的地震仪相当的仪器，同时保留MET地震传感器的其他理想特性：低成本，低功耗，坚固耐用，可批量生产。 这些地震仪预计将在目前采用顶级传统地震仪的所有应用中竞争。 一般来说，这意味着地震学的科学研究和监测。 它们还将用于大型传感器网络应用，坚固耐用，体积小，重量轻，使它们在钻孔和海底特别有吸引力。
