Abstract
A system includes a thin-film battery and an activity-activated switch. In some embodiments, the system is placed on a substrate with an adhesive backing. In some embodiments, the substrate is flexible. Also formed on the substrate is an electrical circuit that includes electronics. The activity-activated switch places the thin-film battery in electrical communication with the circuit and electronics. The battery and the circuit are formed on the substrate and may be comprised of one or a plurality of deposited layers.
