This Small Business Innovation Research Phase II project is aimed at developing an ultra-sensitive magnetic sensor technology that is capable of operation in an unshielded environment. These compact sensors will be based on superconducting quantum interference devices (SQUIDs) that are fabricated from high temperature (high-Tc ) superconducting materials. A collaborative effort between MagneSensors and U.C. Berkeley will employ novel design and materials processing solutions to produce high-Tc SQUIDs operating in ambient fields with an unprecedented level of sensitivity. The program will test the developed sensors on real-world applications at both low and high frequencies to demonstrate operation in the presence of large background magnetic field interference. This new enabling technology seeks to overcome the limitations in sensitivity, bandwidth, size, and spatial resolution, which restrict the more widespread application of present conventional magnetic field sensors. The eventual goal is the development of a low-cost, portable system with much greater sensitivity than is available with any other instrumentation. This technology will enable the development of an entirely new generation of instrumentation that will find use in a wide variety of applications. Such applications include non-destructive evaluation of cracks and corrosion in aircraft, inspection of integrated circuits, homogeneous immunoassays and DNA probes using magnetic labels, geophysical surveying, environmental monitoring, detection of unexploded ordnance, diagnosis of intestinal ischemia, and screening for cardiac arrhythmias The potential market size for some of the applications reaches over $1 billion.

这个小型企业创新研究阶段II阶段项目旨在开发一种能够在非屏蔽环境中运行的超敏感磁性传感器技术。这些紧凑的传感器将基于用高温（高-TC）超导材料制造的超导量子干扰装置（鱿鱼）。 Magnesensors和U.C.伯克利将采用新颖的设计和材料加工解决方案来生产具有前所未有的敏感性水平的环境领域中运行的高-TC鱿鱼。该程序将在低频和高频的现实世界应用上测试开发的传感器，以证明在存在大型背景磁场干扰的情况下运行。这项新的促成技术旨在克服灵敏度，带宽，大小和空间分辨率的局限性，从而限制了当前常规磁场传感器的更广泛应用。最终的目标是开发低成本的便携式系统，其灵敏度要比任何其他仪器所提供的要高得多。这项技术将能够开发全新的仪器，从而在各种应用中找到使用。此类应用包括对飞机中裂缝和腐蚀的无损评估，使用磁性标签，地球物理测量，环境监测，未爆炸的弹药的检测，肠道局部性局部性局部性诊断和筛查$ 1的市场尺寸，以供某些份量覆盖$ 1的市场，对飞机的裂纹和腐蚀性，均匀的免疫测定和DNA探针进行了$ 1的诊断，以供您使用$ 1的市场，以供$ 1的诊断。
