Abstract

A double softening glass drag spinning method (DSGDSM) with thermal furnace heating was developed for fabrication of long glass coated coaxial microwires on the basis of semiconductor and semimetal. The technological path of fabrication of coaxial thermoelectric microwires base on bismuth teluride semiconductors is described. Several mechanical and physical parameters of coaxial wires, which underline their advantages, are presented. The method of manufacture of microthermocouples on the basis of coaxial microwire DSGDSM technology of fabrication is reported. Due to small diameters and thicknesses of thermoconductors as well as glass coating the obtained long coaxial microthermocouples are sufficiently flexible, have high sensitivity and can be used for different thermal management application..
