摘要： A power-generating method of generating power from a power-generating element. An electric polarization state in the power-generating element is changed by phase transition. First, an electric field is applied to the power-generating element to change a phase transition temperature of the power-generating element by an electric-field application unit for applying the electric field to the power-generating element without changing a temperature of the power-generating element. Then, the electric polarization state in the power-generating element is changed by application of the electric field and control of the application, so that the power from the power-generating element is generated.

摘要： A method of making an electrocaloric element includes dissolving or dispersing an electrocaloric polymer in an organic solvent having a boiling point of less than 100° C. at 1 atmosphere to form a liquid composition comprising the electrocaloric polymer. A film of the liquid composition is cast on a substrate, and the organic solvent is evaporated to form a film of the electrocaloric polymer. The film is removed from the substrate and disposed between electrical conductors to form an electrocaloric element.

摘要： The present invention belongs to the technical field of energy conversion devices, which provides an rGO-PEI/PVDF pyroelectric thin film, and the method for preparing the film, as well as a self-energized bracelet produced based on such film, which utilizes the reduced graphite oxide after modified by polyethyleneimine (PEI) (rGO-PEI) as photothermal conversion material, and the silver-plated polarized polyvinylidene fluoride (PVDF) film as pyroelectric conversion material. The rGO-PEI photothermal material is fixed to the surface of the PVDF through a transparent film, and prepare the self-energized bracelet based on it. The obtained bracelet has an output power of up to 21.3 mW/m2, and does not require additional mechanical devices to control the temperature during operation, wherein, the thermoelectric conversion, rectification, storage and application are realized through temperature fluctuation produced by absorbing sunlight during doing outdoor sports, utilizing temperature difference of air flow, and sweeping gesture, etc.
