First Claim
1. A timing device comprising;
- a. an electrochemical structure comprising;
i. a first electrode material;
ii. a second electrode material;
iii. an electrolyte; and
iv. an activating mechanism to activate the electrochemical structure by placing the electrodes in electrical communication with each other, wherein activating the electrochemical structure generates a response from the electrochemical structure to indicate a passage of a duration of time after being activated; and
b. a compensating element electrically coupled to the electrochemical structure, the compensating element configured to regulate the time of the response as indicated by the electrochemical structure in response to changes in temperature.

Abstract
A timing device for indicating the passage of a duration of time is disclosed. The timing device and system, in accordance with the embodiments of the invention, comprise an electrochemical component which generates a visual and/or audio indication of the passage of time. The timing device further comprises a compensating element, such as a varistor, a thermistor and/or combinations thereof. The compensating element regulates the response of the device with respect to changes in temperature. The timing device is configured to indicate the passage of a single duration of time or comprises zones that are activated in a range of prescribed times and individually or collectively indicate the passage of time or the passage of a range of times.
