Optically Pumped Magnetometers from QuSpin Guide Drones & Brain Imaging 

Optically pumped magnetometers have an edge over even some superconducting devices for precision magnetic field detection since they don’t need cryogenic cooling. QuSpin, a company focused on developing atomic devices, has come out with its second-generation sensor for integration into compact aerial and underwater drones. Meanwhile, Cerca Magnetics, a medtech startup is applying QuSpin’s OPM technology to open new capabilities in neurologic imaging. […]

NVE Introduces World’s Most Sensitive Magnetometer IC & More Ultra-Miniature Converters

Billed as the world’s most sensitive magnetometer integrated circuit, the new ALT021-10E analog magnetometer from NVE Corporation has a remarkable sensitivity of 0.5 millivolts per volt per microtesla. Based on the company’s tunneling magnetoresistance (TMR) technology, the device can precisely measure fields from less than a microtesla to 250 microtesla. […]
