1. A wearable action-assist device which assists or executes an action of a wearer by substituting for the wearer, comprising:

  • an action-assist tool having an actuator which gives power to the wearer;

    a biosignal sensor detecting a wearer'"'"'s biosignal;

    a biosignal processing unit acquiring, from the biosignal detected by the biosignal sensor, a nerve transfer signal for operating a wearer'"'"'s muscular line skeletal system, and a myoelectricity signal accompanied with a wearer'"'"'s muscular line activity;

    an optional control unit generating a command signal for causing the actuator to generate power according to a wearer'"'"'s intention by using the nerve transfer signal and the myoelectricity signal which are acquired by the biosignal processing unit; and

    a driving current generating unit generating a current according to the nerve transfer signal and a current according to the myoelectricity signal, respectively, based on the command signal generated by the optional control unit, to supply the respective currents to the actuator.
