Technologies are generally described herein for electrocaloric effect heat transfer devices and methods effective to facilitate heat transfer over a wide operating temperature range of a corresponding heat source. Some example heat transfer devices may include multiple heat transfer stacks with at least two heat transfer stacks having electrocaloric effect materials with varying effective temperature ranges. The combined effective temperature ranges of the multiple heat transfer stacks encompass the operating temperature range of the heat source.
