Biofeedback apparatus using magnetic stimulator and control method therefor

A biofeedback apparatus comprising:

• a pressure transducer which senses a pressure applied from an outside of the pressure transducer by using a fluid and supplies a pressure signal;
• a controller which generates a biofeedback signal by using the pressure signal supplied from the pressure transducer and outputs the biofeedback signal;
• and
• a display unit which outputs the biofeedback signal supplied from the controller on a screen,
• wherein the pressure transducer includes:
• a tube which is configured with a soft material of which shape is variable according to an external pressure and is filled with the fluid;
• a pressure sensor which senses the pressure applied to the tube to output a pressure signal;
• and
• a pressure transfer member which is disposed between the tube and the pressure sensor to transfer the pressure of the tube to the pressure sensor, and
• wherein the controller includes a reference point setting module which receives the pressure signal from the pressure transducer and sets a reference pressure value by using the received pressure signal according to a reference pressure value setting request input from an outside.
