Abstract
A silver-nano electronic-ink print heating element separation-type electric thermotherapy apparatus includes two or more silver-nano electronic-ink print heating elements that emit heat using a power source applied from a power source unit. The electric thermotherapy apparatus includes a control unit which receives the power source from the power source unit to output a power source on-off signal and a temperature control signal for controlling the two or more silver-nano electronic-ink print heating elements, and the silver-nano electronic-ink print heating elements emitting heat depending on the power source and/or a temperature applied using the control unit, whereby an integral heating element, such as an electric mat, an electric mattress, an electric cushion, a hot-water mat, and an electric carpet, includes two or more divided parts, and thus it is easy to separately use the parts of the heating element and to independently control the temperature for the heating parts.
