Claim:
1. A bioelectric signal measurement apparatus, comprising: a first interface including at least one electrode configured to detect a bioelectric signal of a testee through electrical interfacing with a skin of the testee; a second interface including at least one electrode configured to detect only a motion artifact signal different from the bioelectric signal through electrical interfacing with the skin, the at least one electrode included in the second interface electrically interfacing with the skin in a state that is different from a state in which the at least one electrode included in the first interface electrically interfaces with the skin; and a signal processor configured to remove, from the detected bioelectric signal, a motion artifact between the first interface and the skin using the detected motion artifact signal wherein an impedance of the at least one electrode included in the second interface due to the electrical interfacing with the skin is larger than an impedance of the at least one electrode included in the first interface due to the electrical interfacing with the skin.
