EXMAD Experimental setup

EXMAD - Extreme sensitive magnetometry using nitrogen-vacancy centers in diamond

The EXMAD project is an international collaboration targeting development of diamond-based high-resolution quantum sensors for wide-field magnetic imaging. 
Research goal

The nitrogen-vacancy (NV) center in diamond is an artificial atomic system trapped in the diamond crystal lattice. These properties combined with exceptionally long decoherence times makes it a unique system for magnetic field sensing with simultaneous high sensitivity and spatial resolution. EXMAD aims to exploit those properties for development of magnetic field quantum sensing devices for bio-medical applications. The collaboration brings together academic expertise on fabrication and field sensing using ODMR (optically detected magnetic resonance) with industrial partners and partners from the Danish medical sector.

As a first application of the technique, we will record neuron activity by performing magnetic field imaging of brain tissue.


The project is a collaboration between DTU Physics, DTU Electro, University of Copenhagen, Ulm University (Germany), Leipzig University (Germany), Hvidovre Hospital and Philips BioCell.
