VOLUMETRIC RATE OF LIQUID, GAS, OR FREE-FLOWING MATERIAL

Patent Pending A superconducting field effect transistor based transducer (SuFETTr) for the micro- and nanofluidic sensors to measure 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 electrogaseodynamical effects. The range of the calculated signals lies in the range of (-5÷5)V, (7÷0)•10^17/cm^3 molecules, 2÷10 pH, and stream speed 10^2÷10^-3 m/s, flow 10÷10^-5 m/s and hemoglobin concentration of 10^30÷10^24 molec/mm^3. The available operating modes have been explained.
