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 »
DiGioia Gray has launched it’s abandoned oil well seeking machine, WELLSCOUT! WELLSCOUT is a UAV equipped with QuSpin’s QTFM scalar magnetometer. This Aeromagnetic drone can find metallic waste and conduct environmental surveys with incredible efficiency. Check it out. DiGioia Gray Team: Andrew Zorn , Erich V. Zorn
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 »
Matt Brookes and his team take another giant step forward towards building a practical MEG scanner. In their latest work published in Nature [1], E. Boto and coworkers show that not only is it possible to build a high-performance MEG scanner with non-cryogenic sensors (QZFM) but that you can ‘wear’ the scanner and collect data while… Read more »
A promising application of nanoparticles in medicine is magnetic nanoparticle (MNP) based blood purification (MPBP). In this technique, MNPs are functionalized with antibodies that bind to unwanted (preselected) toxins, cells or proteins in the blood. The bound particles are then removed using a strong magnet, thus selectively filtering the blood. For safety reasons, it is important… Read more »
Fetal magnetocardiography (fMCG) is an innovative and emerging diagnostic utility aimed at the early identification of fetal heart problems. Its efficacy for diagnosis and management of serious fetal arrhythmia has been acknowledged in the recent American Heart Association Statement on Diagnosis and Treatment of Fetal Cardiac Disease. In 2016, an experimental fetal MCG system with a… Read more »
Genetesis is developing CardioFlux – a clinical grade Magnetocardiography system powered by QuSpin QZFM sensors. The CardioFlux magnetic shield system is a cylindrical open end design (seen below) capable of attenuating background magnetic noise sufficiently to allow the CardioFlux to be installed in just about any clinical environment. The image below shows initial data recordings… Read more »
We report the latest results from a Wellcome Trust-funded collaborative project between the University of Nottingham and the University College of London investigating OPM based multichannel MEG to be presented at the Workshop on Optically Pumped Magnetometers (WOPM ‘17). Elena Boto and coworkers at Nottingham report, “We have shown the ability to beamform sources to… Read more »
An ideal sensor is stable and exhibits very low drift between the measured value and the actual value, a task often difficult to achieve at low frequencies over long measurement times. Our QTFM attains high, low-frequency stability and high sensitivity by implementing low-noise/low-drift electronics, and by stabilizing to a high degree every operating parameter of the… Read more »
QuSpin’s first public demonstration of our QTFM magnetometer product was at the Navy Forum for SBIR/STTR Transition held April 3-5, 2017 at the Gaylord Convention Center in National Harbor, MD. This demonstration showcased the progress QuSpin has made in the Phase I and Phase II development towards Navy SBIR topic N141-004. The high-sensitivity mags are small, low… Read more »
