项目摘要

DESCRIPTION (provided by applicant): Koronis Biomedical Technologies (KBT) proposes to develop a novel tunneling magnetoresistance (TMR) sensor for use in medical devices. TMR technology delivers improvements in magnetic sensor size, sensitivity, and noise rejection that represent an opportunity to significantly enhance the performance of a variety of medical devices that currently rely on traditional magnetic sensors. These products include pacemakers, implantable defibrillators, neurostimulators, and drug pumps. Further applications include probe localization, audio transmission, and telemetry. Integrating TMR sensors into medical devices will result in smaller, more powerful, and more efficient systems. This is evidenced by TMR's adoption in the magnetic recording industry, which has increased magnetic data storage densities by three orders of magnitude through the development of TMR read heads. KBT will design, fabricate, and test an optimized TMR sensor, adapting this technology for use in medical applications. A hearing aid telecoil replacement testbed application that will demonstrate the ability of TMR sensors to receive magnetic audio signals will be developed and tested. PUBLIC HEALTH RELEVANCE: The development of tunneling magnetoresistance (TMR) technology has had a transformative impact on the magnetic recording industry by dramatically increasing storage density using smaller, more sensitive, and more noise resistant magnetic sensors. This technology can be applied to similarly improve medical devices, including hearing aid telecoils. The adaption of TMR sensors for these devices will place sensors with superior performance in very small and previously inaccessible locations.

描述（由申请人提供）：Koronis Biomedical Technologies（KBT）拟开发一种用于医疗器械的新型隧道磁阻（TMR）传感器。TMR技术在磁传感器尺寸、灵敏度和噪声抑制方面提供了改进，这代表着有机会显著增强目前依赖传统磁传感器的各种医疗设备的性能。这些产品包括起搏器、植入式起搏器、神经刺激器和药物泵。其他应用包括探头定位、音频传输和遥感勘测。将TMR传感器集成到医疗设备中将产生更小，更强大，更高效的系统。这通过TMR在磁记录工业中的采用得到了证明，通过TMR读取头的发展，磁记录工业将磁数据存储密度增加了三个数量级。KBT将设计、制造和测试一种优化的TMR传感器，使该技术适用于医疗应用。将开发和测试一个助听器拾音线圈更换试验台应用程序，该应用程序将证明TMR传感器接收磁性音频信号的能力。公共卫生关系：隧穿磁阻（TMR）技术的发展通过使用更小、更灵敏和更抗噪声的磁传感器来显著增加存储密度，对磁记录行业产生了变革性影响。这项技术可以应用于类似的改进医疗设备，包括助听器拾音线圈。将TMR传感器用于这些设备将使传感器在非常小且以前无法到达的位置具有上级性能。
