Abstract Electrocaloric effect has attracted considerable attention for providing an eco-friendly and energy-efficient alternative to traditional vapor-compression refrigerators. In this review, we introduce theoretical explanations of positive and negative electrocaloric effects along with their measurements. In particular, we review recent advancements in prototypes of electrocaloric refrigeration and present their current advantages and shortcomings. Finally, we discuss the potential applications of the electrocaloric effect such as clothing and metamaterials to provide insights into future research.

Altmetric calculates a score based on the online attention an article receives. Each coloured thread in the circle represents a different type of online attention. The number in the centre is the Altmetric score. Social media and mainstream news media are the main sources that calculate the score. Reference managers such as Mendeley are also tracked but do not contribute to the score. Older articles often score higher because they have had more time to get noticed. To account for this, Altmetric has included the context data for other articles of a similar age.
