Project Description

Magnetoencephalography (MEG) is a non-invasive brain imaging method, where images of the electrical activity inside the brain can be generated. It measures the magnetic field that comes out of the head with an array of magnetic field sensors placed all around the head. We are developing quantumÌı magnetometers for this application. These sensors are also starting to be used for brain-computer interfaces, where movement is essential. Currently the sensors reach their best performance in a low magnetic field environment. The objective of this project is to develop a dynamic low-field environment with sets of magnetic field coils. A current ME/CE senior design team is developing a prototype system of the coils. The goal is to steer the field zero dynamically using the signal from magnetic field sensors.It will require programming control loops (together with a computer science master student), designing and building improved coils, and measuring and testing the system.
