Abstract
Section titled âAbstractâSensing devices used in (aero)space are constrained by energy consumption, mass, volume and environmental \ncompatibility. Although quantum sensors offer potentially better sensitivity than classical sensors, they are bulky and \noften require cooling to cryogenic temperatures or operation in vacuum. Here we propose a technical realization of a \nquantum sensor for magnetic field detection based on nitrogen-vacancy (NV) centers in diamond, which is compatible \nwith miniaturization and offers potential sub-picotesla sensitivity. The miniaturization is based on recently developed \nelectric readout of the NV center electron spin resonance. Our engineering platform allows to use diamond chip as a \nportable magnetic field sensor. We have designed and tested a miniaturized prototype and describe all key components \nfor technical miniaturization. We achieved a power consumption down to 3.5 W, a weight of the fully integrated sensor \nof only 27g and small dimensions of 45 x 25 x 25 mm including all driving and readout components. We have proved \nthe chip functionality in vacuum and explored its thermal behavior. The system will be further used for on-board \nstratospheric balloon experiment. The miniaturized sensor we developed has potential applications in a wide range of \nfields including navigation, bio-signal measurement, material analysis or space weather monitoring and planetary \nobservation.
