Double microthermocouple made on the basis of BI2TE3 microwires for biomedical research

Abstract

Development of the technology for manufacturing miniature device for microscopy investigation of various biological objects with the possibility of changing their temperature in the direction of its increase and decrease is important. Due to very good thermoelectric performance at room temperature the BiTe microwires in glass coating for constructing this device were selected. Most frequently for materials of n-type conductivity the alloys Bi2Te3-xSex(x=0.1’1) are utilized. As thermoelectric material of p-type conductivity, the alloys (Bi2Te3)1-x(Sb2Te3)x commonly used.
