Magnetic Fields

Though invisible to the eye, magnetic fields permeate the world around us. These fields pass unaffected through most objects, such as water, rock, walls, and the human body, which allows us to look through many objects, opaque to light. At FieldLine we are building sensors systems that image these fields with higher precision than has ever been done. But, we go beyond simply measuring these fields. We are implementing sophisticated algorithms based on AI and machine learning to extract meaningful information. The information generated by our systems can be used in a variety of applications:

  • Passive imaging of brain function
  • Security applications
  • Non-destructive testing of structures and infrastructure
  • Brain computer interfaces

Next Steps…

One of the exciting applications is the next-generation of magnetoencephalography (MEG), a non-invasive brain imaging technology. Through highly sensitive uncooled miniature magnetic field sensors, MEG can advance from static cryogenically-cooled systems to lightweight conformal helmets, to clearer images, and novel studies through the patients that can move freely. With cost-sensitive sensor technology, we envision the day where an MEG system is available in every major hospital.
