Biological signal measurement device and method for controlling biological signal measurement device

Abstract

A biological signal measurement device includes a dry-type electrode; a member configured to fix the electrode in a state in which the electrode is pressed against a living body; and a control body configured to measure a biological signal by the electrode. The control body includes a waveform feature extraction unit configured to extract a feature amount from a waveform of the biological signal, and an attachment state determination unit configured to determine whether an attachment state of the electrode is good or poor, based on a feature amount extracted from a waveform of a biological signal measured during a period after an elapsed time from attachment of the electrode to the living body by the member reaches a predetermined time.
