Abstract
A temperature sensor includes a plurality of rectangular shaped amorphous magnetic alloy strips connected magnetically, wherein at least one of the strips has a predetermined ferromagnetic Curie temperature, and another strip has a magnetic permeability well exceeding 2,000. The temperature sensor may be used in a related remote temperature sensing method wherein the sensor is interrogated by a magnetic field and the temperature sensor's response signal is detected electromagnetically.
