Abstract
A temperature regulation system includes a laminate material that has a first light transmissive electrode layer, a rear electrode layer, and a bistable electrophoretic medium disposed between the first and second electrode layer. The electrophoretic medium includes two types of particles that have different charges and color. The amount of incident radiation (visible light, infrared, etc.) that is absorbed by the laminate can be modified by providing a voltage between the electrode layers.
