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.

Abstract: The present invention relates to a tracking-type photovoltaic generator. More particularly, the present invention relates to a tracking-type photovoltaic generator in which multiple solar modules are aligned into one or more rows so as to form a group, and the solar modules of the group aligned in the same row may rotate according to the location of the sun by means of the operation of a linear actuator.

Abstract: Provided is a high-effective concentration photovoltaic solar tracking device and method; and, more particularly, to a concentration photovoltaic solar tracking device and method, which maximize concentration efficiency by concentrating solar light using a Fresnel lens and moving a solar panel based on focus information formed when the concentrated solar light is irradiated on a photodiode.

Abstract: The present invention relates to a technology for printing a thin film transistor (TFT) using single walled carbon nanotubes coated with dielectric substance having a thickness of several nm and thus capable of improving significantly a low on/off ratio of an existing single walled carbon nanotube TFT.
