Hereinafter, a bodily sensation induction system including a cushion induction type soot 100 and a laser irradiation apparatus 300 according to the present invention will be described with reference to FIG.

Referring to FIG. 1, the bodily sensation induction system according to the present invention includes two configurations, that is, a feeling-inducing sole 100 to be directly worn by a user and a laser irradiation apparatus 300.

The inexpensive induction sole 100 according to the present invention irradiates a laser beam irradiated from the outside to cause the body tissue of the wearer to have physical And a bodily sensation inducing area 200 for inducing a sensation. At this time, the bodily sensation inducing area 200 is formed of a medium 250 capable of inducing a sense of body in the skin tissue of the user. The laser is irradiated to one surface of the medium 250, And is driven by the principle that the body sensation is induced in the skin tissue of the wearer as an effect of the action generated by the laser to be irradiated.

In addition, the medium 250 forming the bodily sensation inducing region 200 induces a somatosensitivity to the wearer's skin differently depending on the pattern of the laser beam. At this time, the somatosensitivity can be recognized by the wearer or the user It is preferable to be derived in the form of a specific pattern. The shape of the pattern can be communicated to each other such as to be able to distinguish a specific direction, amount or magnitude of a number, strength, etc., or to guide a route, such as speed, proximity to a destination, All patterns can be included.

The principle of inducing the somatosensory to the wearer's skin tissue in the sensory guiding sole 100 according to the present invention is that the medium 250 forming the bodily sensation inducing area 200 receives the laser from the laser irradiation apparatus 300 A series of action effects triggered by the laser occurs. The effect of this action is transmitted to the skin tissue of the user and driven in such a manner as to induce a bodily sensation. This will be described in more detail with reference to FIGS. 3 to 5, which will be described later.

Meanwhile, the bodily sensation inducing area 200 may be formed in a total area or a partial area contacting the wearer's skin of the body-facing sole 100. The bodily sensation inducing region 200 is formed of a medium 250 that generates a stress wave by absorbing laser energy. The medium 250 is a surface contacting the wearer's skin such as the abdomen, back, shoulder, arm, So that a tactile sensation can be induced in the corresponding portion.

The laser irradiating apparatus 300, which is another major constituent of the present invention, is configured to apply a series of actions and effects on the medium 250 forming the bodily sensation inducing area 200 by irradiating the laser of the in- . As will be described later, the laser irradiating apparatus 300 can irradiate a laser to the bodily sensation inducing region 200 on the soot, and irradiate the laser according to a predetermined pattern. That is, the laser irradiation apparatus 300 can control the irradiation direction of the laser to be internally irradiated, and accordingly, the direction of the laser irradiated on the bodily sensation inducing region 200 can be controlled to draw a certain pattern. For example, the laser irradiating apparatus 300 may irradiate a laser according to a pattern having a directivity, thereby inducing a user to perceive the direction. The laser irradiating apparatus 300 may further include a bodily sensation inducing region 200, that is, a bodily sensation inducing type stimulable phosphor, such as a bodily sensation inducing type stimulable phosphor, by controlling various parameters of the laser such as the intensity, pulse width, pulse duration, It is possible to cause the soot 100 to be irradiated with a predetermined pattern, that is, ultimately to induce a somatic sensation of a certain pattern in the user's skin tissue.

Meanwhile, the laser irradiating apparatus 300 according to the present invention may be carried by a user directly or may be worn as a device, or may be installed as a separate device in the ship 1000 or the submersible as in Embodiment 1 described later have.

2 is a block diagram showing the detailed configuration of the laser irradiation apparatus 300 described above. Referring to FIG. 2, the laser irradiation apparatus 300 includes a laser output unit 310, a frequency control unit 320, an energy control unit 330, a diameter control unit 340, and a control unit 350. Meanwhile, in order to implement the laser irradiation apparatus 300 at this time, the control unit 350 and the laser output unit 310 are essentially included, and other functional units may be included or excluded according to the needs of the user.

First, the laser output unit 310 may include a laser driver and a cooling device for outputting a pulse laser. The laser driver may include a sub-device such as a laser medium 250, an optical pumping device, an optical resonator, etc., and generates an optical signal for implementing a pulsed laser. In addition, the cooling device cools the heat generated by the laser driver in the process of generating an optical signal, and prevents malfunction due to overheating of the laser driver.

In addition, the laser output unit 310 may be implemented in various ways to generate a pulsed laser. For example, a ruby laser, a neodymium: YAG laser, a neodymium: glass laser, a laser diode, an excimer laser, a dye laser, or the like. For reference, it is noted that a neodymium: YAG laser is used to generate a pulse laser in the experimental example described below.

Next, the frequency control unit 320 controls the pulse frequency per unit time of the irradiated laser. Assuming that the output of the laser is one cycle when the output of the laser is high and one time when it is low, the frequency controller 320 controls the frequency of the unit time, for example, several pulses per second You can set whether to include the cycle, and the user can control the frequency of the pulsed laser through this setup.

In the meantime, it should be understood that the pulse laser frequency in the present invention is freely controllable from 1 Hz to 70 Hz. Further, when a frequency is 0 Hz, that is, a single shot, Can be set.

Next, the energy control unit 330 functions to control the energy intensity of the irradiated laser. The energy intensity is expressed in millijoules (mJ), and the energy intensity in the present invention can be preferably controlled from 0 mJ to 30 mJ.

Meanwhile, the energy control unit 330 may be realized by an optical filter, which may include an attenuator for attenuating the intensity of the pulsed laser.

Next, the diameter control unit 340 controls the diameter of the irradiated laser or accurately focuses the laser to a target point to be irradiated.

The diameter control unit 340 may be embodied as a convex lens for converging the laser beam to one point and a concave lens for diffusing the laser beam. The distance between the convex lens and the concave lens is selectively controlled to focus The diameter of the laser can be controlled.

Finally, the laser irradiation apparatus 300 further includes a control unit 350 for controlling the laser output unit 310, the frequency control unit 320, the energy control unit 330, and the diameter control unit 340 described above do.

The control unit 350 may include at least one computing unit and a storage unit, and the computation unit may be a general-purpose central processing unit (CPU) or a programmable device element (CPLD, FPGA ), An application specific integrated circuit (ASIC), or a microcontroller chip. In addition, a volatile memory element, a non-volatile memory element, or a non-volatile electromagnetic storage element may be utilized as the storage means.

Meanwhile, it is preferable that the wavelength of the laser mentioned in the present specification is any one of 445 nm, 480 nm, 532 nm, 650 nm, 809 nm, 850 nm and 1064 nm. The laser wavelength is relatively easy to implement as compared with other wavelengths, which is advantageous in that laser irradiation can be easily controlled. It is to be understood, however, that the laser wavelength in the present invention is not limited to the above specific values, and that the numerical value of the laser wavelength may be varied within a range that can be readily implemented by a person skilled in the art.

Hereinafter, referring to FIG. 3, the principle of guiding the body sensation in the bodily sensation inducing area 200 of the cushy guided sole 100 according to the present invention will be described.

Referring to FIG. 3, the bodily sensation area 200 according to the present invention includes a medium 250 having two surfaces, in which a laser beam is irradiated on one side of the medium 250, Characterized in that the medium (250) induces a somatosensory to the skin tissue of the user as an effect of the action caused by the laser.

More specifically, the medium 250 is a material having an adhesive property. The medium 250 may have various compositions, but may be made of an acrylic foam. Also, at this time, the medium 250 may be a semi-liquid or an elastic material, which is clearly solid or liquid, preferably as a pressure-sensitive adhesive, or the medium 250 may be a fully synthetic polymer, . &Lt; / RTI >

The bodily sensation inducing area 200 according to the present invention is formed of a medium 250 having the above characteristics. This is because the bodily tissues of the user, that is, By irradiating the medium 250 without irradiating the laser directly to the medium 250, the medium 250 generates a series of action effects based on the energy received by the laser, thereby inducing a sperm sensation in the user's skin tissue . Conventionally, a laser for minimizing irritation to biological tissues has been devised. However, such a laser has a problem that the magnitude of a stimulus induced in a living tissue is not large when irradiated directly to human tissue. In order to solve such a problem, the present invention proposes a method in which a medium 250 is brought into contact with a living tissue and a laser beam is irradiated thereto.

I) irradiating the skin tissue of the user with the medium 250 through the medium 250, i) it is possible to induce heat and thermo-elastic effects without individual differences by reducing the influence of the characteristics of the living tissues for each person ii) (Iii) a laser that irradiates by placing a new component called a medium (250), which is a medium, such as a laser The type of the medium 250 or the thickness of the medium 250 that can be bonded can be varied in the same laser condition. So that the effect can be induced.

4 shows the medium 250 constituting the bodily sensation area 200 according to the present invention in more detail. Referring to FIG. 4, the medium 250 of the present invention is formed of two layers. In this case, the absorption coefficients of the medium 250 can be adjusted by varying the color of each layer during manufacture. Hereinafter, a portion directly absorbing a laser is referred to as a first layer 251, and a portion contacting a skin tissue of a user is referred to as a second layer 255. [

As a method of controlling the absorption coefficient of the medium 250, there is a method of changing the color of the layer as mentioned above. As shown in FIG. 4, when the first layer 251 and the second layer 255 are respectively composed of a red-red medium or a red-white medium 250, in each case So that the medium 250 has different absorption coefficients.

In this case, the absorption coefficient means a coefficient indicating the degree to which the medium absorbs light. In general, the absorption coefficient is related to monochromatic light, and the value depends on the wavelength of light.

Considering the above definition of the absorption coefficient, the medium 250 in the present invention can control the wavelength of the absorbed laser and the absorption of the wavelength depending on how the color of each layer is selected. For example, when the first layer 251 is red, this red color medium acts to increase the absorption coefficient for green (a wavelength range of 575 nm to 492 nm in visible light), which is a complementary color of red color. On the other hand, if the second layer 255 is white, this white medium generally serves to lower the absorption coefficient for all wavelength regions. Therefore, when the first layer 251 and the second layer 255 are all formed of red, the absorption coefficient for the wavelength of the green series becomes higher than that of the medium composed of red-white. On the other hand, according to the present invention, it is to be understood that when a laser is irradiated on the medium depending on which medium of the material is used, the tactile sensation transmitted to the user may vary. In other words, in addition to the above-mentioned acrylic foamed foam material medium, it is also possible to transmit the touch, the feeling of vibration, and the warmth to the user's skin tissue which is contacted by using the medium of aluminum material and the blue medium coated with the adhesive agent on the synthetic fiber . The fact that the senses felt by the user can be changed according to the material of the medium to be used in this way means that more kinds of senses can be provided to the user by the physical properties inherent to each medium and various laser parameter combinations.

For example, in the case of an acrylic foamed foam material, the user has a mechanical feel, while in the case of a medium coated with a viscous agent on a synthetic fiber, the user has a feeling of mechanical touch and warmth In the case of the aluminum medium, the user can only feel the mechanical feel of very weak strength.

FIG. 5 is a side view of the medium 250 in the present invention, showing the layer structure thereof. Referring to FIG. 5, the medium 250 includes a first layer 251 and a second layer 255 stacked in a plane, and an adhesive layer 253 between the first layer 251 and the second layer 255. [ As shown in FIG.

When the laser beam is irradiated onto the medium 250 in the bodily sensation inducing area 200, three kinds of action effects are generated in the medium 250, and the thermal elastic effect, the plasma effect, and the heat transfer effect .

First, the thermoelastic effect is a mechanism by which the medium 250 in the bodily sensation area 200 according to the present invention is most used to induce tactile sensation in the user's skin tissue. Specifically, when the laser having a very short pulse width is absorbed by the medium 250, the absorption region of the medium 250 is locally heated by the laser absorption momentarily, The pressure is increased locally while thermally expanding, and at the same time, a pressure wave is generated and the energy is transferred to the surrounding medium 250. That is, when the laser is incident on the medium 250, the light energy distribution in the medium 250 is changed by the optical system number (absorption coefficient, scattering coefficient, refractive index, and anisotropy coefficient) And the stress wave at this time is the pressure wave described above, and the energy is transmitted to the surrounding medium 250. Mechanical deformation such as local expansion or pressure increase of the medium 250 which is expressed in the above-described series of processes enables the user's skin tissue, i.e., living tissue, in contact with the medium 250 to feel a touch.

On the other hand, the magnitude of the stress wave generated and propagated in the medium 250 by the laser absorption is determined according to the following equation.

In this case, p _max is the maximum magnitude of the incident stress, c _s is the velocity of the sound wave, μ _a is the absorption coefficient of the medium (250), Γ is the grating constant, and H ₀ is the absorbed fluence .

According to the above equations (1) and (2), it is necessary to increase the maximum size of the stress wave to induce a larger tactile sensation in the body tissue. It is preferable to use the medium 250 having a high absorption coefficient and a high Grundigan constant.

On the other hand, at this time, the Gruenian constant is an index indicating the degree of change of the energy of the phonon (quasi-particle representing the quantized vibration of acoustic quantum and crystal lattice) according to the thermal expansion as a intrinsic constant of the medium (250) crystal.

On the other hand, in view of the acoustic impedance of the medium 250, the transmission coefficient at the boundary surface of the medium 250 is generally defined by the following equation (3)

In this case, p _t is the magnitude of the stress wave passing through the medium 250, p _i is the magnitude of the stress wave incident toward the medium 250, and Z ₁ is the refractive index of the first medium 250, And Z ₂ represents the acoustic impedance of the second medium 250, which is the medium 250 in the direction in which the stress waves are emitted. In this case, acoustic impedance means a value obtained by dividing a pressure on a plane parallel to the wavefront by a volume velocity of a wave passing through the wavefront when the wave propagates. In other respects, the acoustic impedance refers to the resistance that a wave receives as it passes through the medium 250.

According to Equation (3), it is preferable that the acoustic impedance of the second medium 250 is larger than the acoustic impedance of the first medium 250 in order for the stress wave to pass through the medium 250 more easily. That is, when the two mediums 250 are in contact with each other, the acoustic impedance Z 1 of the first medium 250 into which the wave is incident is small and the acoustic impedance of the second medium 250, The transmission coefficient T becomes high when Z2 is large.

That is, when the present invention is applied to the present invention, it is preferable that the medium 250 has an acoustic impedance which is smaller than the acoustic impedance of the body tissue (skin).

In addition to the previously mentioned thermoelastic effect, the medium 250 further generates a plasma effect and a heat transfer effect as the laser is irradiated. As a result of this effect, the skin texture of the user, which is in contact with the medium 250, Pressure or warmth can be induced.

As for the plasma effect, when a laser is irradiated, a plasma is generated. In the medium 250 due to induced plasma, an acoustic emission phenomenon occurs. The acoustic emission phenomenon is a phenomenon in which when the solid is deformed, the strain energy stored therein is released to generate an acoustic wave, and a sudden energy is locally released in the medium 250 by the laser irradiation, It refers to the phenomenon.

The heat transfer effect is a phenomenon in which thermal energy transferred from the surface or inside of the medium 250 is transferred. As a laser is irradiated on the medium 250, the temperature of the medium 250 is increased. To the skin tissue of the user during the process of transferring the heat energy to the surrounding medium 250.

However, these effects may be affected by the properties of the medium 250, that is, the physical properties of the medium 250. In other words, the effect of the heat elastic effect, the plasma effect, The degree of expression varies depending on whether a particular effect appears prominently or not.

For example, assuming that the first layer 251 of the medium 250 to which the laser is irradiated is the same medium 250, depending on the physical properties of the second layer 255, a thermoelastic effect, a plasma effect, or a heat transfer effect The present invention aims to induce a variety of body senses to the user by utilizing the difference in the effect expressed according to the physical properties of the medium 250 as described above.

3 to 5, a bodily sensation inducing region 200 in the diving suit 100 according to the present invention, more precisely, a medium 250 forming the bodily sensation inducing region 200, And to induce somatosensory sensation.

Divers who are active in the water, or divers who enjoy diving as leisure, spend a lot of time in the water, but it is not easy to communicate with each other in the water.

There may be many unexpected situations during underwater activities, and thus communication between the divers in the water, between the diver and the ship (1000), and between the diver and the diver is still a necessity. Conventionally, a radar has been used to communicate with each other in water or a radio equipment provided separately. However, there is a problem that the above-mentioned conventional underwater communication means are not suitable for smooth communication in water, or the activities of the divers are greatly restricted.

For example, a receiver must visually view each other, but in many cases it is difficult to expect a visibility with high visibility in the water. Also, when a diver wears separate radio equipment, the weight of the equipment adds to the activity of the diver There is a limitation problem.

The ship 1000 and the submarine manager may control the laser irradiation apparatus 300 to be irradiated Several properties of the laser can be controlled. For example, the manager may control the frequency size to be lower as the interval becomes longer and inform the diver that the distance between the diver and the destination is higher It can be easily understood.
