A one-dimensional magnetoelectric sensor array for magnetic sketching

ORAL

Abstract

Although various magnetic sensors have been developed, it is still a challenge to get the imaging of magnetic objects safely and instantaneously, for example, magnetic imaging for capsule positioning, endoscope navigation, and detection of magnetic weapon that is hidden in/on human body. In this paper, a magnetic detecting and sketching system utilizing a one-dimensional magnetic sensor array with 56 magnetoelectric (ME) sensing units is proposed. The ME sensors used in this system are based on a (1-1) connectivity Metglas/piezo-fiber composite operating in longitudinally magnetized and transversely poled (L-T) mode. Simulation and experiment results show that the proposed magnetic detecting system not only can find the 2-D position of a running magnetic metal object, but also can identify its posture and length-diameter ratio. The proposed magnetic detecting method promises an outlook for medical magnetic positioning and security checking.
