Drones to get new miniature magnetometer

Leti recently completed a high-performance miniature magnetometer prototype suitable for drones. The device, whose probe measures just 8 cm3, is extremely compact. The development was inspired by the magnetometers developed for the space industry in recent years—for the Swarm satellite, for instance—but features some major innovations, like replacing the usual piezoelectric motor with a liquid crystal polarizer to allow the polarization to rotate from 0 to more than 300 degrees. A similar magnetometer is being developed for magnetocardiography and magnetoencephalography. It will operate at ambient temperature, unlike the SQUID magnetometers currently in use, which must be cooled using liquid helium.
The development of this new magnetometer will continue under a Ph.D. thesis in progress with Clinatec.
