摘要：
A method for bioelectric physiological signal acquisition includes:/a/ providing an autonomous bioelectric physiological signal acquisition device including an electrode and an acquisition chain associated to the electrode,/b/ acquiring an analog signal representative of a bioelectric physiological signal with the electrode,/c/ amplifying the analog signal by an amplification factor via a programmable analog amplifier of the acquisition chain,/d/ converting the amplified analog signal in a digital signal via an analog digital converter of the acquisition chain,/e/ processing the digital signal to determine whether the digital signal is considered saturated, if the digital signal is considered saturated,/f/ selecting, in a list of predefined amplification factors, an amplification factor lower than the amplification factor currently applied to the digital signal by the programmable analog amplifier, and/g/ updating the amplification factor of the programmable analog amplifier to the selected amplification factor.
