Kulenko S. Signal Transducers of Heat Flow Sensors for Biomedical Using

A research object is a process of measuring of thermal streams on the basis of construction of signal transducers of thermal microelecronic controls of stream. The article of research is a structure, mathematic models, shemotechnic of microelectronic heat sensory devices of stream. The purpose of work is a increase of sensitisation and discriminability of measuring of thermal streams on the basis of development algorithmically of structural approaches at the construction of sygnal transducer of thermal microelectronic controls of stream. Research methods: mathematical and computer design for the analysis of physical processes, proccessing of signals. A scientific novelty is consist than suggested new approaches of electro-thermal simulation of self heated measurement transducers are proposed. The approaches provide math analysis of ampere-voltage characteristics modulation of thermo resistor, diode and transistor transducers under theirs self heating provided by supply current. Quantity characteristics of heat flow sensors' measurement circuits' efficiency, as well as, the ways of increasing sensors' sensitivity are proposed. Optimal modes of difference temperature sensors' differential transistor stages are determined. The practical value of the got results consists in them that advanced a family of heat flow sensor signal transducers what are based on novel microelectronics element base. A degree of introduction is results dissertation work inculcated in the Medical Center "Gamma-7" (Vinnitsia). Thesis performances are inculcated in an educational process by the Vinnytsia National Technical University. A sphere (industry) of the use is medical and policlinic establishments.
