Abstract: Provided is a far infrared ray-radiating and electromagnetic wave-shielding heating wire using a graphene plate. The heating wire includes: one core wire formed by binding several strands of threads, each of which has a graphene plate conductive layer formed therein; and a plurality of strands of heat wires covered by a covering material and wound around the outer surface of the core wire. Accordingly, when the heating wire is heated by supplied power, heat conductivity is improved, so that electricity consumption in an electric heating product is reduced and the effect of radiating far infrared rays and shielding electromagnetic waves is enhanced. In addition, even when the heating wire is bent and transformed according to the use of the product, disconnection and the risk of fire caused thereby are prevented, so that usage stability of an electric heating product group to which the heating wire is applied is enhanced.

Abstract: Provided is a three-dimensional wave generating device and a multifunctional motion bed having the same. A safety device prevents a driven pulley and/or a driven pulley to which an eccentric shaft is coupled from being separated from a coupling shaft. Therefore, operation stability is secured while noise caused by separation or unstable coupling of the driven pulley and/or eccentric shaft in a three-dimensional wave generating device is prevented from occurring, and when a functional motion bed to which the three-dimensional wave generating device is applied is provided, the user can feel a three-dimensional wave more effectively in bed.
