ABSTRACT:
A method for making a transparent electrothermal body includes: a) plating ITO (indium tin oxide) onto a surface of a transparent substrate to form an ITO film, and b) printing a conducting material onto a surface of the ITO film to form two connecting portions each electrically connected to the ITO film, thereby forming a transparent electrothermal body. Thus, the transparent electrothermal body includes a circuit made of ITO material having greater transparency to form a conducting film that allows passage of the electric current, thereby enhancing the transparency of the electrothermal body, and thereby increasing the versatility of the electrothermal body.
