1. Electrical impedance detector for measurement of physical quantities, in particular of temperature, which detector comprises electrodes (11, 14), between which the electrical impedance (C;

  • R) that represents the physical quantity to be measured is measured, and between which electrodes (11,

         14) there is an active material whose impedance properties are a function of the physical quantity to be measured, characterized in that the active material of the detector is a very thin thread-like glass-ceramic fibre (10) which has been manufactured by means of the glass-drawing technique.
