1. A biosignal-measuring device, comprising:

  • a first information acquisition module configured to acquire a pulse wave signal from a subject at a first position;

    a second information acquisition module configured to acquire an electrocardiogram signal from the subject at a second position different from the first position;

    a first calculation module configured to calculate a pulse wave velocity based on signals acquired by the first information acquisition module and the second information acquisition module;

    a second calculation module configured to calculate a heartbeat interval based on the signals acquired by the first information acquisition module and the second information acquisition module;

    a third calculation module configured to calculate a relational expression between the pulse wave velocity and the heartbeat interval;

    a heartbeat interval estimation module configured to estimate an estimated heartbeat interval based on the pulse wave velocity and the relational expression;

    a determination module configured to determine whether a position of at least one of the first information acquisition module or the second information acquisition module has changed based on the heartbeat interval and the estimated heartbeat interval; and

    an output module configured to output a notification based on the determination of the determination module.
