Abstract
A non-invasive apparatus and method for measuring a temperature of a portion of a living body, includes a signal receiving unit receiving electromagnetic wave signals emitted from the portion of a living body to be measured, a signal processing unit processing the electromagnetic signals input from the signal receiving unit and outputting a radiation power signal, a medium characteristic measurement unit measuring a value of a conductivity or a permittivity of the portion of the living body to be measured and outputting the measured value, and a temperature conversion unit including a computer database storing a plurality of temperature conversion tables with respect to radiation power according to the conductivity or the permittivity of the portion of the living body and determining a corresponding temperature using the measured value of the conductivity or the permittivity of the portion of the living body and the radiation power signal of the signal processing unit.
