Abstract

An electrical device is provided, including a substrate, an electrical component on the substrate, and a battery on or integrating the substrate for providing electrical energy to said electrical component. An open switch prevents electrical communication between the electrical component and the battery while open. A circuit activating component is adapted to irreversibly close the open switch to thereby establish a permanent electrical circuit between the electrical component and the battery.
