US 2012/0055918 A1 · HEAT-GENERATING FILM, AND HEAT-GENERATING PRODUCT COMPRISING SAME

Abstract

The present invention relates to a heat-generating film and to a heat-generating product comprising same. The heat-generating film of the present invention can continuously and stably generate heat even at a low voltage, for example, at a voltage of 12V or lower. In addition, the heat-generating film of the present invention has excellent comfort properties, filling properties, and flexibility. Accordingly, the heat-generating film of the present invention can be applied to a variety of heat-generating products, for example to a heat-generating sheet for a vehicle or for a baby stroller, or to a variety of portable heat-generating products or the like to exhibit superior effects.

Dependent claims

A heat-generating film comprising:

a base sheet;
a heat-generating layer which is formed on the base sheet and has one or more heat-generating parts patterned in a linear configuration;
and an electrode layer comprising a first main electrode and a second electrode which are patterned on the base sheet in a linear configuration perpendicular to the heat-generating part having the linear configuration and formed at the both ends of the base sheet respectively, and one or more auxiliary electrodes which are extended from the first and second main electrodes in a direction parallel with the heat-generating part.

Dependencies are inferred from the claim text.
