Overview
The non-contact and sensitive measurement of minute magnetic fields and currents could enable ground-breaking innovations in microelectronics, biomedicine, materials science and nanoscience. Optical quantum sensors based on nitrogen-vacancy (NV) diamonds have the potential to measure minute magnetic fields with high sensitivity and local resolution. Applications in non-contact inspection of critical metallic and magnetic components and integrated circuits can benefit from the sensitivity and resolution of NV technology. It is expected that biomedical measurement systems for the detection of electrical brain/heart and muscle currents will be greatly improved by NV quantum sensors.
As part of a concept study, an experimental demonstrator for imaging measurement of magnetic fields with precise spatial resolution based on NV diamonds was investigated. As a demonstration, the current distribution of conductors in printed electronics was measured with high resolution. Our current research is investigating different approaches to increase the measurement sensitivity and precise spatial detection of the magnetic field for applications in non-contact inspection and biomedicine. Working with project partners, we are translating the latest scientific findings into significant innovations and tangible improvements.
