Abstract
A radio frequency (RF) multibit tag structure useful for identifying objects of interest is described. An array of thin cantilevers of slightly different lengths produced by differential etching are coated with a soft magnetic material which upon interrogation with an RF magnetic field vibrate at their resonant frequencies in the presence of an appropriate bias or direct current (DC) field. The oscillating magnetic fields generated by the vibrating bars and the stationary DC field can be readily detected by a receiver and processed to determine the code of the tag and thus provide information related to the object.
