Abstract
An elapsed time indicator comprises a porous element, an electrical source, and an electronic controller. The electronic controller is configured to receive electrical power from the electrical source and cause a fluid to be received by the porous element in response to expiry of a predetermined time period. The predetermined time period may be associated with an item such as a perishable item with which the elapsed time indicator is to be associated or to which the elapsed time indicator is to be attached. The predetermined time period may comprise a lifetime or a shelf-life of the item or a predetermined proportion of a lifetime or a shelf-life of the item.
