ELECTROCALORIC REFRIGERATOR AND MULTILAYER PYROELECTRIC ENERGY GENERATOR

摘要

Provided are electrocaloric devices, pyroelectric devices and methods of forming them. A device which can be a pyroelectric energy generator or an electrocaloric cooling device, can include a first single-layer heat engine having a first side configured to be in contact with a first reservoir and a second side configured to be in contact with a second reservoir, wherein the first reservoir comprises a fluid. The device can also include a second single-layer heat engine having a first side in contact with the first reservoir and a second side in contact with a third reservoir and a channel disposed between the first single-layer heat engine and the second single-layer heat engine, the channel configured to transport the fluid from a first end to a second end. The device can further include one or more power supplies configured to apply voltages to the first and the second single-layer heat engine.
