A superconducting field-effect transistor (SuFET) based neurotransducer (sensor) with carbon nanotubes (CNT) or pickup coil kind of input circuit for the nerve and neuron impulse has been designed. Electronic or ionic currents in conductors or axons respectively, passing through the SuFET’s channel induce the output voltage on its gate. The method of combining the bioelectric nature of NSs with body-temperature PC and zero resistance input of the SuFET device in order to obtain most advantageous biosensor/transducer was recently advanced. The SuFET is used as a zero-resistance ammeter which converts drain currents into gate voltages. A nanoSuFET with a high-temperature superconducting channel is introduced into the nerve fibre or brain tissue for transducing their signals in both directions. Pickup coils are implanted into an organism in order to obtain the natural neurosignals from the organs and tissues, also the artificially excited signals to them. The range of picked up signals varies from 0.6 nA to 10 µA with frequencies from 2 to 2000 Hz.
