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.

该小型企业创新研究第二阶段项目旨在开发一种能够在非屏蔽环境中运行的超灵敏磁传感器技术。这些紧凑型传感器将基于由高温（高温）超导材料制成的超导量子干涉器件（SQUID）。 MagneSensors 和 U.C. 之间的合作努力伯克利分校将采用新颖的设计和材料加工解决方案来生产在环境场中运行且具有前所未有的灵敏度的高温 SQUID。该计划将在低频和高频的实际应用中测试开发的传感器，以演示在存在大背景磁场干扰的情况下的操作。这种新的使能技术旨在克服灵敏度、带宽、尺寸和空间分辨率方面的限制，这些限制限制了当前传统磁场传感器的更广泛应用。最终目标是开发一种低成本、便携式系统，其灵敏度比任何其他仪器高得多。这项技术将促进全新一代仪器仪表的开发，该仪器将用于各种应用。此类应用包括对飞机裂纹和腐蚀的无损评估、集成电路检查、使用磁性标签的同质免疫测定和 DNA 探针、地球物理测量、环境监测、未爆炸弹药检测、肠道缺血诊断以及心律失常筛查。一些应用程序的潜在市场规模超过 10 亿美元。
