Abstract: Devices, systems, and methods for controlling acquisition of a signal representing a physiological measurement are described herein. An example device comprises: an input for receiving the signal in digital form, wherein the signal has been acquired by means of at least one electrode without galvanic contact between the electrode and the living being and has been processed by circuitry for acquisition of the signal in analog domain to refine the signal before the signal is converted from analog to digital domain; an adaptation decision module, being configured to determine whether a measure of signal quality indicates that an adaptation of the circuitry for acquisition of the signal in analog domain is beneficial for the robustness of the system and/or the quality of the obtained signals; wherein the adaptation decision module, is arranged to output a control signal for controlling a parameter affecting amplifier saturation in processing of the signal.

Abstract: A system for the acquisition of biopotential signals, comprising at least a first electrode configured for detecting a biopotential signal within a signal bandwidth of interest and being connected to an impedance detection module that provides a first electrode voltage. The impedance detection module comprises a current generation circuit connected in parallel to an amplifier. The current generation circuit comprises an AC current generator configured to generate a first current signal through the first electrode. The first current signal has a frequency outside of the signal bandwidth of interest. The current generation circuit also comprising a capacitor connected between the input of the amplifier and the AC current generator so as to isolate the AC current generator from the amplifier input at the signal bandwidth of interest. The system also including a signal processor configured to calculate a component value of a first and a second electrode-tissue impedance based on a difference between the first electrode voltage and a second electrode voltage.
