    Abstract: A deformation sensing sensor as disclosed includes a conductive material inside the body thereof such that, by sensing a change in resistance or capacitance resulting from a deformation, a degree of deformation of the measurement object can be detected. The body includes an elastic layer, which has a corrugation formed on one surface thereof, and a conductive layer, which is formed on the other surface of the elastic layer using a conductive material. When the body is deformed in the lateral direction of the surface on which the corrugation is formed, the change in resistance of the conductive layer before and after the deformation, or the change in capacitance thereof is measured, thereby detecting the degree of deformation of the measurement object.

    Abstract: An embodiment relates to a heat transfer device including a heat generating device configured to generate heat having predetermined intensity by a user, a cover in contact with a body of the user while covering the heat generating device, and a heat transfer medium provided between the heat generating device and the cover to transfer the heat generated by the heat generating device, wherein the heat transfer medium is a structure that is formed by entangling a single wire having a predetermined length and has a predetermined width and a predetermined height, and is a structure that is compressed in an axial direction when being in contact with the body of the user and thus has a Poisson's ratio of 0.5 or higher. Thus, a structural change in the heat generating device is not required and only a material in contact with the heat generating device is changed, so that generated heat may more rapidly reach the body of the user.
