Abstract
Small, low-cost wireless temperature sensors () are provided for sensing the temperature of an object (). The temperature sensors () preferably include a plurality of individual, magnetically susceptible temperature sensor elements (-), as well as optional magnetic field-responsive data elements () adapted for attachment to object () or to a substrate () in turn attached to object (). The temperature sensor elements (-) preferably have magnetic bodies () exhibiting a re-magnetization response under the influence of an applied alternating magnetic field, which is different below and above a set point temperature, normally the Curie temperature of the magnetic body () or an adjacent sheath (). The temperature sensors () are used in conjunction with a detector () operable to generate a magnetic field of magnitude sufficient to cause re-magnetization responses of the temperature sensor elements (-) and optional data elements (), to detect such responses, and to use the detected responses to determine the temperature of object () by means of a decoding algorithm. The temperature sensors () can be used in closed-loop heating systems () capable of controlling the heating of an object ().
