The microfluid sensors of liquids, gases, and tissues based on the CNT or organic FETs

A superconducting field effect tronsistor bosed transducer (SuFETTr) for the micro- and nanofluidic sensors to measurs the electrical currents and mechanical flows has been described. SuFETTr device consists of either CNT or organic FETs with a superconducting property. The flowmeters are based on a common or superconducting induction sensors employing the magnetohydrodynamical and electrogase dynamical effects. The range of the calculated signals lies in the rangę of - (5^5) V, (7+0) •10 17cm3 molecutes, (2^10) pH, and stream speed (10 2+10 -3) m/s, flow (10 1-10 -5} m/s and hemoglobin concentration of (10 30 +10 24)molec/mm3. The ovailable cperating modes have been explained.
