摘要： The present invention describes a tag comprising a magnetic element in the form of a microwire of 80-250 microns with giant magnetoimpedance which, when joined to an object, allows for the wireless detection of same by modulating the reflectivity of the microwire. Detection is performed by using a system that emits an electromagnetic wave that has a frequency between 1 and 20 GHz and a low frequency magnetic field (0.01-50 Hz), and detects the modulation of the reflectivity of the microwire. Thus, objects at distances greater than 1 m can be detected.
