1 to 4, the glove 100 for virtual reality and augmented reality according to an embodiment of the present invention includes a glove sheet 110, a plurality of sensor pattern units 120, a controller 130, and a wiring pattern. The unit 140 is included.

The glove sheet 110 may be formed in the shape of a glove so as to be worn on a user's hand, is in close contact with the hand when worn, and may be formed of a material having a predetermined elastic force. The glove sheet 110 may include a first layer 111, a second layer 112, and a third layer 113 as shown in FIG. 2.

The first layer 111 may form an outer surface of the glove sheet 110, and the second layer 112 may form an inner surface of the glove sheet 110. Here, the first layer 111 may include urethane, and the second layer 112 may include polyethylene terephthalate (PET). The third layer 113 may be interposed between the first layer 111 and the second layer 112 to attach the first layer 111 and the second layer 112 to each other. This third layer 113 may comprise an adhesive or double sided tape.

In the glove sheet 110, the first layer 111 may have a thickness of about 0.175T, the second layer 112 may have a thickness of about 0.2T, and the third layer 113 may have a thickness of about 0.125T. It may be made of a thickness of T. However, in the present embodiment, the thicknesses of the first layer 111, the second layer 112, and the third layer 113 are not limited as described above, but may be changed to various values.

Meanwhile, the wiring pattern unit 140 may be formed on the first layer 111, and a coating layer (not shown) may be formed. The coating layer (not shown) may protect the sensor pattern portion 120 and the wiring pattern portion 140 and may be fixed to the first layer 111.

The plurality of sensor patterns 120 are patterned with a conductive material in a paste state at a position corresponding to the finger joint of the glove sheet 110, and the resistance value changes according to a change in the length L thereof. can do. Each of the sensor pattern units 120 may include a first electrode pattern 121, a second electrode pattern 122, and a plurality of sensor body patterns 123.

The first electrode pattern 121 and the second electrode pattern 122 may be formed in a line shape and may be arranged to be parallel to each other in a direction crossing the finger portion of the glove sheet 110. For example, the first electrode pattern 121 and the second electrode pattern 112 may be disposed to cross in a direction substantially perpendicular to the length direction of the finger portion of the glove sheet 110. In this way, when the user bends the finger after wearing the glove 100 for virtual reality and augmented reality, the first electrode pattern 121 and the second electrode pattern 122 are extended by a finger joint so that a change in length does not occur. can do. In addition, the first electrode pattern 121 and the second electrode pattern 122 may be spaced apart from each other at a predetermined interval.

Thus, the sensor body pattern 123 is a resistor. If the length (L) increases, the resistance value of the sensor body pattern 123 also increases. However, since the cross-sectional area decreases as the length L of the sensor body pattern 123 increases, a constant change in the resistance value occurs according to the strain of the length L of the sensor body pattern 123.

5 is a test result data showing the change in the line resistance value according to the strain (or stretching ratio) of the sensor pattern portion according to the embodiment of the present invention, the existing sensor and the sensor pattern portion 120 of the present embodiment (sample name: FTL -365H) Resistance characteristic curves for each strain [%] are shown.

As shown in FIG. 5, the sensor pattern unit 120 measured a resistance value of about 506 kV up to 130% strain. That is, the sensor pattern unit 120 according to the present embodiment can be stably operated on the resistance value without breaking even if it is increased to 130%.

<Table>

The sensor pattern unit 120 may include a nano paste (about 0.3 nm), a micro paste (3 μm), and a viscous conductive agent. Here, silver (Ag) may be used as the conductive paste, ECA (Ethyl Carbitol Acetate) may be used as the viscous conductive agent, and polyester (Polyester) may be used as the binder material.

The conductive paste and the viscous conductive agent may be formed of the sensor pattern part 120 through a pattern printing and drying process according to a predetermined composition ratio and printing conditions. For example, the solid content of the conductive paste may be about 83 ± 3%, the viscosity of the viscous conductive agent may have 14,000 ± 2,000 cps, and thixotropy may indicate 4.0 ± 0.5, but Only one example, it can be produced in various conditions.

The resistance value of the second sensor pattern part may be measured through the measurement, and the resistance value of the third sensor pattern part may be measured by measuring the voltage of the terminal connected to the third sensor pattern part of the sensor connection part 131. Accordingly, the resistance measuring unit 132 may determine how much resistance value is measured in which sensor pattern unit 120.

The pattern strain calculator 133 may calculate strain for each length of the sensor pattern unit 120 according to a resistance value calculated by the resistance measurer 132. For example, as shown in FIG. 5, the characteristic information of the resistance value according to the strain of the sensor pattern unit 120 is stored in advance, and the resistance value measured through the resistance measurement unit 132 is based on the stored lookup table. It can be calculated by estimating the strain.
