Abstract: The present invention relates to an acellular skin substitute for breast reconstruction and a preparation method therefor. In the present invention, an acellular skin substitute may be prepared through the removal of epidermal layers and an acellularization process, in which the use of a proteolytic enzyme and a surfactant is excluded. In addition, since the acellular skin substitute is cut into suitable sizes and shapes to cover a breast reconstruction implant through design software and then cut out with a CNC machine, the time for breast reconstruction surgery may be reduced, and since no dead space is formed after suturing, the incidence of seromas may be reduced. Accordingly, the side effects of surgery may be lessened.

Abstract: Discloses is a smart opening and closing apparatus. More particularly, the smart opening and closing apparatus includes an opening/closing means configured to be opened or closed depending upon application of a stimulus, a fixation means configured to maintain an open state of the opening/closing means by selectively interfering with the opening/closing means depending upon application of a stimulus, and a controller configured to control opening/closing of the opening/closing means by applying a stimulus to the opening/closing means and the fixation means and, in a state in which the stimulus is released, to control the fixation means to interfere with the opening/closing means so as to maintain a shape of the opening/closing means. In accordance with such a configuration, the shape of the opening/closing means may be maintained also in state in which a stimulus is not applied, whereby low-power operation may be accomplished.
