9860219 This Small Business Innovation Research (SBIR) Phase I project will explore the manufacturability of economical, broad-band, wide dynamic range, triaxial force-balance accelerometers, using unique tribo-electric transducers with liquid dielectric inertial masses. Their performance is expected to compare well with conventional force balance accelerometers, while affording lower cost, low power consumption, and rugged construction. This accelerometer would find use in measurement of strong ground motion in areas of high seismicity as a supplement to conventional seismometer data, in instrumentation of civil structures in earthquake prone areas for recording large dynamic loads, and for various other industrial applications. It may also be extended to include purely rotational accelerometers.

9860219 这个小型企业创新研究（SBIR）第一阶段项目将探索经济，宽带，宽动态范围，三轴力平衡加速度计的可制造性，使用独特的摩擦电传感器与液体介电惯性质量。 它们的性能有望与传统的力平衡加速度计相媲美，同时提供更低的成本，低功耗和坚固的结构。 这种加速度计将用于测量高地震活动性地区的强地面运动，作为传统地震计数据的补充，用于地震易发地区的民用结构的仪器测量，以记录大的动态载荷，以及用于各种其他工业应用。 它也可以扩展到包括纯旋转加速度计。
