Abstract
Provided is an energy harvesting device using pyroelectric materials. The energy harvesting device includes a first heat source; a second heat source having a temperature higher than a temperature of the first heat source; and a cantilever which is interposed between the first heat source and the second heat source, the cantilever including a first film formed of a pyroelectric material and a second film, where the first film is disposed on the second film and a thermal expansion coefficient of the second film is different from that of the pyroelectric material of the first film. Electric energy is generated by periodically changing a temperature within the first film.
