The present invention relates to a design method of smart clothing based on electromyography using anthropometric information.

Electromyography is a method for quantifying the degree of contraction of skeletal muscle that controls body movement. It is smaller in size than other signals such as electrocardiogram, and due to noise and crosstalk of the signal due to movement, the measurement site and method In accordance with this, it must be attached at the exact location where the signal can be extracted.

In particular, it is important to accurately attach the surface electrode to the muscle to be measured because it is difficult to measure the activity of a muscle located in a deep place due to a greater cross-muscular noise in the signal to be measured compared to the insertion electrode. The accuracy of the electrode attachment position brings limitations to the development of clothing that can be applied to various human bodies and body types.

An object of the present invention is to provide a method for designing EMG-based smart clothing suitable for individual body characteristics by utilizing representative measurement items of the human body.

The body measurement information may be at least one of height, chest circumference, waist circumference, shoulder width, and hip circumference.

The pattern may be a circular pattern designed by a close-fitting clothing pattern design method using the body measurement information.

The EMG electrode attachment position may be specified using one or more reference points and reference lines on the pattern.

Through the method of manufacturing smart clothes based on electromyography according to the present invention, the position of the electromyogram electrode on the clothing pattern can be accurately derived by using body measurement information such as height, chest circumference, waist circumference, and hip circumference, which are representative human body measurement items. Through this, smart clothing based on electromyography can be designed to fit an individual's body size.

Furthermore, according to the manufacturing method of the present invention, it is possible to more accurately measure the EMG information of the smart clothing wearer by deriving the optimal position of the EMG electrode for each body type suitable for each individual body characteristic, and to minimize the crosstalk of the EMG signal. can

The length of the line segment connected to the point may be located at a point LD having a length of 10 cm in height.

Further, the electrode for measuring the electromyography of the biceps femoris is a straight line that passes vertically through the midpoint of the hip circumference baseline (b-b2) of the back plate, and a point moved 5 cm from the midpoint of the back side line of the thigh to the groin point (c2). , may be located at the point BF where a straight line perpendicular to the center line intersects.

In the present invention, the electrodes capable of measuring the EMG of the quadriceps, adductors, gluteus maximus, and biceps femoris can be placed in an accurate position by the method as described above, whereby the EMG measurement as shown in FIG. As shown in FIG. 7 and a pattern for smart clothes with electrodes installed, smart clothes bottoms with electrodes for measuring electromyography can be obtained. At this time, the electric wire represented by the curve in FIGS. 5 and 7 serves to electrically connect the power and controller parts of the smart clothing represented by a rectangle and the electromyography electrode (circle). The adjunct may optionally be present and may have a different shape. For example, the power supply and controller shown in FIG. 7 may be designed in an integrated type rather than in a form that is attached to each left and right, and by changing the location (thigh, abdomen, etc.) and attachment direction (front part, side part, rear part, etc.) can be attached.

As described above, according to the present invention, smart clothing can be designed so that the position of electrodes for EMG measurement can be accurately placed using body measurement information such as height, chest circumference, waist circumference, shoulder width, hip circumference, etc. For example, the electrode attachment position for EMG measurement may be specified using one or more reference points and reference lines on the upper, sleeve, and lower patterns of the smart clothing. Accordingly, crosstalk of the EMG signal can be minimized and an accurate EMG signal can be collected.

Furthermore, according to the method of the present invention, it is possible not only to provide ready-made EMG clothing, but also to make personalized smart clothing, so that in the future, the on-demand system is introduced in the automated customized clothing production process. can be actively used.
