Sensors With a Bioelectronic Connection

The method and devices (SuFETTrs) for design of the bioelectronic sensors has been proposed. The method is based on combining the artificial sensors and organs of the senses with a nerve system of living beings for receiving recalibrated output signals. The circuits consist of the superconducting organic or solid-state field-effect transistor (SuFET) connected to a nerve fiber by the low-ohmic or nanotubes contacts. Application of organic, chemical and carbon nanotubes (CNT)-based FETs for design of SuFETTrs is the proposed area of research. The range of picked up signals varies from 0.6 nA to 10 muA with frequencies from 20 to 2000 Hz. The output signal lies in the range of -5divide5 V, (7divide0)middot10¹⁷/cm³ molecules and 2divide10 pH. The placement of the SuFETTr devices can be carried out both in vivo and in vitro with the possibility of forming the controlling signals s from the said quantities. Interaction between sensors and bioelectronic or mechatronic system in order to obtain input and output signals from brain and motor nerves to the external devices or organs and vice versa for processing or environmental control is also presented in the scheme
