  • Publication number: 20090292255
    Abstract: A micro-needle patch has microneedles extending from a first main surface, which is made of a material including chitin and/or chitosan. The micro-needle patch has a feed substance on at least one of the first main surface and a second main surface. The micro-needle patch makes insertion of the microneedles into a living body easier. The micro-needle patch is manufactured by pressing a plate having a recessed pattern on a surface thereof, the recessed pattern including recesses corresponding to micro-needles of at least one micro-needle patch, against a sheet or film of a raw material to form protrusions corresponding to the recesses on a surface of the sheet or film.

  • Publication number: 20090234301
    Abstract: A method for producing a microneedle includes feeding a resin fluid to a forming mold having a needle-forming portion with an opening diameter of 50 to 200 ?m and a depth of 100 to 500 ?m, charging the fed resin fluid into the needle-forming portion, and cooling and solidifying the charged resin fluid. The feeding, the charging, and the cooling and solidification are performed under reduced pressure or vacuum.

  • Patent number: 7397444
    Abstract: A two-dimensional (2D)/three-dimensional (3D) convertible display using a pinhole array, and more particularly, a 2D/3D convertible display, which is easily convertible between the 2D or 3D modes using an electro-optic material of which the refractive index varies according to applied power is provided. A system capable of easily selecting 2D/3D can be used in many fields, which are in need of greatly improved video information, such as medical science, engineering, simulation, and stereoscopic video TV, which will emerge in the near future.
