SBIR Phase I: High Performance Very Broad Band Seismometerswith Magnetohydrodynamic Feedback

*** 小行星9761485 这个小型企业创新研究（SBIR）第一阶段项目将探索磁流体动力学反馈和频谱转换，以创建一个新的一类非常宽的频带，宽动态范围的地震仪。 新仪器将基于分子电子技术（MET），由电解质上的磁流体动力学效应提供力平衡反馈，电解质充当惯性质量。 通过使用信号调制来产生频谱平移，将实现彻底的降噪。 第一阶段将开发一种性能与最好的传统技术地震仪相当的仪器，同时保留MET地震传感器的理想功能，例如，低成本、低功耗、坚固耐用、适合批量生产。 这些地震仪有望在目前使用最先进的传统地震仪的地方找到商业应用。 它们的低成本使得它们在大型传感器网络和教育应用中特别有吸引力。 ***

*** 9761485 Abramovich This Small Business Innovation Research (SBIR) Phase I project will explore magnetohydrodynamic feedback and spectrum translation to create a new class of very broad-band, wide dynamic range seismometers. The new instruments will be based on molecular electronic technology (MET), with force balancing feedback provided by the magnetohydrodynamic 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. Phase I will develop an instrument equal in performance to the best traditional-technology seismometers while retaining desirable features of MET seismic sensors, e.g., low cost, low power, ruggedness, and suitability for volume production. These seismometers are expected to find commercial applications wherever top-of-the line traditional seismometers are currently employed. Their low cost makes them particularly attractive for use in large sensor network and education applications. ***
