An electrophysiological sensor, weak electrical signal conditioning circuit and method for controlling the circuit as provided. The sensor includes rigid filiform conducting nanostructures connected to a conducting substrate and operable to penetrate an organic tissue. The circuit includes an instrumentation amplifier with an input connected to a first electrode in contact with a first area of a medium, and a second input; a voltage generating device connected to an electrode in contact with a second area of the medium for applying a continuous reference signal to it; a compensator, electrically insulated from the device, for compensating the direct current offsets of a weak electrical signal received by the first electrode, generating a signal with a reference voltage with a value which can be modified by a control system, and supplying it to the second input. A method is also provided for controlling the circuit.
An electrophysiological sensor of the type which is based on conducting nanostructures which can transmit a weak electrical signal captured from the skin or from another part of an organic tissue to a transmitter means for transmitting said weak signal, said sensor comprising a plurality of said nanostructures which adopt a rigid filiform configuration and are chemically connected at one end to a conducting substrate electrically coupled to said transmitter means, being operable to at least partially penetrate said organic tissue or skin at their free end.
A method for controlling a weak electrical signal conditioning circuit, comprising:
