Patent number: 11402212Abstract: Motor vehicles use biomagnetic sensors to determine global position by detecting Earth's geomagnetic field. Magnetosensitive bioparticles, such as magnetotactic bacteria or organelles from a magnetoreceptive eukaryotic species, are dispersed in a gel medium. The magnetosensitive bioparticles generate a local magnetic moment that changes in response to fluctuations in the immediate geomagnetic field vector, the latter of which is dependent on global position. An integrated circuit, such as an array of superconducting quantum detects changes in the local magnetic moment, and a controller thereby determines the ambient geomagnetic field vector. The controller accesses a database having a correlation of geomagnetic field vector and geolocation.Type: GrantFiled: March 23, 2018Date of Patent: August 2, 2022Assignee: Toyota Research Institute, Inc.Inventor: Abraham S.
