Somatic sensation induction system using pulse laser and medium of high absorption coefficient
The present invention relates to a system for fundamentally eliminating skin damage caused by direct radiation of a laser beam on the skin of a user and inducing a somatic sensation on the skin within a safety standard by radiating a pulse laser beam on a medium attached to the skin of the user on which the somatic sensation is desired to be induced. Particularly, the present invention relates to a somatic sensation induction system which can induce a somatic sensation of various feelings delivered to a user by adjusting an absorption coefficient of a medium contacting with the skin of a user, energy intensity and a repetition rate of a radiated laser beam and the like.
1. A somatic sensation induction system comprising:
a laser radiation device for controlling parameters of a laser beam and radiating the laser beam on one side of a medium; and
the medium, one side of which is radiated with the laser beam, and the other side of which contacts with a skin tissue of a user,
wherein the medium includes a first layer and a second layer which are disposed in a stacked structure between the laser radiation device and the skin tissue of the user,
wherein each of the first layer and the second layer has a different color and absorbs a different wavelength of laser beam so that a numerical value of the absorbed wavelength and an absorbed degree of the absorbed wavelength are adjusted depending on the color of each of the first and second layers, and
wherein each of the first layer and the second layer has an acoustic impedance smaller than an acoustic impedance of the skin tissue.
2. The system according to claim 1 , wherein the parameters of the laser beam include energy intensity, pulse width, pulse frequency, stimulation time or beam diameter.
3. The system according to claim 1 , wherein the first layer or the second layer is in red color or white color.
4. The system according to claim 3 , wherein the wavelength of the laser beam is one of 445 nm, 480 nm, 532 nm, 650 nm, 809 nm, 850 nm and 1064 nm.
5. The system according to claim 4 , wherein the first layer and the second layer are respectively in red color and white color, and a sensation of touch is induced on the skin tissue of the user by controlling a pulse frequency of the laser beam between 1 Hz and 25 Hz.
6. The system according to claim 4 , wherein the first layer and the second layer are respectively in red color and white color, and a sensation of vibration is induced on the skin tissue of the user by controlling a pulse frequency of the laser beam to be 25 Hz or higher.
