Energy harvesting

Pyroelectricity gain in multilayers

Nature Energy volume 7, pages 1007–1008 (2022)Cite this article

Subjects

Pyroelectric materials have potential applications in sensors and energy harvesters but it is difficult for these materials to deliver energy in the joule range. Now, a pyroelectric harvester made of lead scandium tantalate with a multilayer structure is shown to generate about 4.43 J cm–3 from each thermodynamic cycle.
