Latest Patents

Ciureanu holds a patent for a "Magnetic field sensor with enhanced sensitivity, internal biasing and magnetic memory." This invention describes a high sensitivity magnetic field sensor that utilizes a stress-sensitive, negative-magnetostriction, melt-extracted amorphous wire. The sensor operates by developing a strong magneto-impedance effect when connected to conventional electronic circuitry, such as an impedance-meter. The design includes an a.c. current supplied to the wire, with its relative change in impedance measured while subjected to a longitudinal d.c. magnetic field. A saturating d.c. field pulse is applied at the beginning of the operating cycle, and tensile stress is generated in the wire to fine-tune sensitivity and bias. The entire system is packaged in a rugged non-magnetic enclosure for reliable connections.
