ABSTRACT:
A timing device for indicating the passage of a duration of time is disclosed. The timing device in accordance with the embodiments of the invention comprises an electrochemical component that generates a visual and/or audio indication of the passage a duration of time. The electrochemical component preferably comprises two or more electrode structures that sandwich a suitable solid-state electrolyte. In an alternative embodiment of the invention, a timing device comprises an electrochemical component with an indicating electrolyte and an indicating layer that absorbs or reacts with the indicating electrolyte when an electrode material is depleted, providing a visual indication of the passage of a duration time.
