Abstract
A heated tray which can be activated to release a frozen liquid from compartments thereof. The tray includes an electrically insulative body having one or more compartments for receiving a liquid to be frozen. The tray also includes an electrically conductive polymer which can be heated by applying a potential across the conductive polymer. The conductive polymer is provided so as to be adjacent each compartment of the insulative body. The tray further includes first and second electrode grids on either side of the conductive polymer, which electrode grids include electrode members that are adjacent each compartment of the insulative body. The first and second electrode grids and the conductive polymer form a circuit which is used to heat the compartments of the insulative body.
