Timing system and device and method for making the same
First Claim
1. A timing device comprising an electrochemical structure, the electrochemical structure comprising a solid-state electrolyte and electrodes in electrical communication with the solid-state electrolyte, wherein depletion of one or more of the electrodes provides an indication of a passage of a duration of time, further wherein the electrochemical structure is divided into zones, wherein the zones are made to have different rates of reactivity, that collectively provide a visual indication of the passage of the duration of time.

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.
