Abstract

The magnetomodulation differential weak magnetic-field sensor, based on the Bi-2223 high-temperature superconducting ceramics has been investigated. The high magnetic-field resolution (~20 pT) and wide measurement range (125 - 140 dB) have been obtained. The possibility of using this sensor for noninvasive control of magnetic particles or implanted medical electronic devices in biological objects at a distance of up to 30 mm from the skin surface is discussed.

Keywords: high-temperature superconducting ceramic; magnetic-field sensor; magnetic-field resolution; noninvasive control; medical implants.
