Quasar Federal Systems has developed compact, portable electric and magnetic field sensors that operate without mechanical or electrical contact with their surroundings and can withstand extreme environments. The sensors are sensitive enough to measure the possible earthquake-precursor low-frequency electromagnetic waves. The technology can measure static and dynamic stress in rock and boreholes and measures all six components of the magnetic and electric fields at low frequency. Integrated with DA hardware and GPS timing for real-time output, the system is in its final stages of data gathering and testing.
