1. A portable biosignal measurement apparatus to be worn by a user, the apparatus comprising:
- a control unit to control a fluid;
a pressure supplier including a cuff to apply a pressure in a direction of a radial artery of the user'"'"'s wrist by the fluid, which is flowed depending on the pressure;
a fastening unit to fasten the portable biosignal measurement apparatus around the user'"'"'s wrist when the apparatus is worn by the user;
a support member, disposed on a portion of an upper surface of the fastening unit and a portion of a lower surface of the control unit; and
a sensor unit to sense a biosignal using displacement of the radial artery,wherein the cuff is disposed between the support member and the sensor unit, and the support member supports the cuff to apply pressure in a direction of the radial artery, andwherein the control unit comprises a micro pump to apply pressure to the fluid using a motor, and a vessel to contain the fluid and to transfer the fluid from the vessel to the cuff by pressure which the micro pump applies using the motor,wherein the sensor unit includes a pressure sensor disposed between the cuff and the radial artery of the user when the apparatus is worn by the user, andthe control unit houses the micro pump using the motor, the vessel containing the fluid, and a measurement control unit to measure the biosignal.

11. A method for measuring a biosignal, the method comprising:
-
storing a fluid in a vessel of an article worn by a user; controlling a flow of the stored fluid from the vessel into a cuff portion of the article using a micro pump with a motor; applying a pressure in a direction of a radial artery of the user'"'"'s wrist by the fluid transferred to the cuff, by using the micro pump with the motor to apply pressure to the fluid in the cuff; supporting the cuff by applying pressure in a direction of the radial artery, by using a support member disposed on a portion of an upper surface of a fastening unit which fastens the article around the user'"'"'s wrist and a portion of a lower surface of a body housing the micro pump with the motor; and measuring a biosignal of the user, by using a sensor unit, wherein the cuff is disposed between the support member and the sensor unit, and the sensor unit includes a pressure sensor disposed between the cuff and the radial artery of the user, wherein the body housing the micro pump with the motor also houses the vessel containing the fluid and a measurement control unit to measure the biosignal. - View Dependent Claims (12, 13, 14)
