bio-feedback mat

The present invention relates to a biofeedback mat.

Recently, as people's interest in health care increases, exercises such as yoga, gymnastics, squats, push-ups, and stretching are spreading, and auxiliary devices for these exercises are widely distributed in the market.

As one of the auxiliary devices, there is a mat for exercise, and the mat for exercise is used to reduce the pressure on a specific part of the body by the weight of the body and a specific part of the body in contact with the floor during exercise. Such an exercise mat is generally configured to include a cushioning material made of natural rubber or synthetic foaming agent, and an outer skin made of natural fibers or synthetic resin, so that the outer skin surrounds the cushioning material.

Such exercise mats do not have a function to provide feedback on whether the user is taking a correct posture or exercising properly when taking a posture or exercising. A problem arises.

However, it is preferable to increase the sensitivity of the pressure sensor unit 12 and to be configured to be somewhat thin so that the vibration generated by the vibration module unit 13 can be easily felt.

The pressure sensor unit 12 is configured to sense a position and pressure strength that is pressed when the user takes a posture or exercises on the mat unit 10 . The sensing principle of the pressure sensor unit 12 is not limited, and a strain gauge type metal pressure sensor, a piezoresistive pressure sensor, a piezoelectric pressure sensor, a MOSFET type, a piezo junction type, an optical fiber pressure sensor, and a capacitive pressure sensor and the like, and a known configuration may be employed according to the sensing principle.

For example, when the user performs a squat exercise, the start of the squat exercise is transmitted to the control unit 22 through the application of the user terminal, and when the squat exercise is started, the pressure sensor unit 12 detects the pressure position and pressure strength. It is measured in real time and transmitted to the control unit 22, and the control unit 22 compares the time-dependent pressure position and pressure strength information in the correct squat posture.

For example, when a voltage is applied to an electrode in a specific vertical direction and an electrode in a specific horizontal direction, a potential difference is generated at the intersection, and accordingly, the piezoelectric material layer at the intersection is deformed to generate vibration. The larger the potential difference, the stronger the vibration can be generated.
