Overview
Contactless measurement of smallest magnetic fields and currents is important for microelectronics, medicine and bio-, nano- and material sciences. Optical quantum sensors based on nitrogen-vacancy (NV) diamonds have the potential to sensitively measure and locally resolve weak magnetic fields. Within the scope of a concept study, an experimental demonstrator using NV diamonds for precise magnetic field measurement and imaging the magnetic field distribution will be investigated and developed. This will involve the measurement of current distribution in printed electronics. We will push the limits of sensitivity and resolution compared to the state of the art and develop an approach to integrate the technology into a pen.
