MagNimbus: An all-in-one solution for UAV based magnetic detection

Summary: SPH Engineering, based in Latvia, has developed an easy-to-use UAV magnetometer payload with integrated peripherals. The system is available with QTFM in single-sensor and gradiometer configurations. With the development of compact, low-power, lightweight, and highly sensitive magnetometers like the QTFM, conducting high-resolution surveys of magnetic signatures across large land areas has become increasingly feasible,… Read more »

Neuro-1: An integrated sensor system for OPM-MEG

Introducing Neuro-1, a state-of-the-art, integrated optically pumped magnetometer (OPM) sensor system designed for high-channel density biomagnetic applications such as Magnetoencephalography (MEG). This all-in-one solution combines QZFM sensors, control electronics, data acquisition, and power supply into a streamlined, unified system. A key advance in Neuro-1 (N1) is the miniaturization and integration of sensor control electronics. Thanks… Read more »

QZFM Gen-3

The third-generation QZFM sensor (Gen-3) is now ready for release! This is an important milestone that marks the final step in our three-step process to develop mature zero-field OPM technology. The Gen-1 sensor (2016) was a technology demonstrator built to validate the underlying technology. The Gen-2 sensor (2019) was a miniaturized version that paved the… Read more »

New Triaxial QZFM

Our current Gen-2 QZFM can sense y and z components of the magnetic field but not x. Because many applications can greatly benefit from a sensor that can detect all three components, we have developed a new triaxial variant. The triaxial variant has the same size, weight, power, and cost as the standard variant. The… Read more »

Experimental MEG Cap

A number of groups, including us, are exploring what an OPM-based MEG system will look like in the future. The technology is evolving rapidly so it is difficult to make a prediction but an EEG cap-like solution does look promising in the short term. In the photo below we explore a prototype MEG cap with… Read more »

A small, low-cost Magnetically Shielded Room

Magnetoencephalography (MEG) and other biomagnetic recordings are generally made inside a magnetically shielded room (MSR) to suppress environmental magnetic noise. Traditional MSRs built for superconducting MEG systems are very large (for example 3.9 x 2.9 x 2.3 m) and cost around $1M. Optical MEG systems, such as QZFM based MEG, can be very compact and do not require such… Read more »

QZFM Discussion Group

We are starting a long overdue discussion/support page for QZFM (QZFM discussions). Here you will find answers to basic technical queries, and you can post questions, results, tips and any other information useful for the general community. It will take some time to create an exhaustive database but your inputs will go a long way… Read more »

QZFM Gen-2 (Update)

The second generation QZFM sensor (Gen-2) is finally ready for release. In this upgrade, we focussed on mainly two things: (i) reducing the size and weight of the sensor, and (ii) improving manufacturability to support faster production speeds. Along the way, we squeezed out a little more sensitivity and extended the sensor tolerance to background magnetic fields from… Read more »
