SUPERIOR
When superior magnetoresistance crosses your mind – a new path to image brain activity.
About the project
We can get a deeper understanding of how the brain functions by detecting the tiny magnetic fields produced by the brain. A simple way to measure a magnetic field is using magnetoresistive sensors, where a magnetic field is measured by the resistance change it causes in the sensor. However, magnetoresistive sensors are still not sensitive enough to detect the ultra-weak magnetic fields generated by the neurons in our brains.
In this project, we aim to solve this problem by understanding how to control the flow of electrons in a magnetic field. We will use this knowledge to develop a new type of magnetoresistive sensors, aimed at outperforming any other magnetoresistive sensor. If successful, this will be a breakthrough in magnet field sensing that can be used in several areas including detection of brain disorder or magnetic nanoparticles.
