Abstract
A system includes a thin-film battery and an activity-activated switch. 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.

A system comprising:
- a substrate;
- a circuit connected to the substrate;
- a thin-film battery connected to the substrate and connected to the circuit, the thin-film battery for powering the circuit;
- and
- an acceleration-enabled switch connected to the substrate for electrically activating the circuit;
- wherein the acceleration-enabled switch is a MEMS device;
- wherein the acceleration-enabled switch includes:
- a first cantilevered-beam-closure-switch;
- and
- a second cantilevered-beam-closure-switch;
- wherein the first cantilevered-beam-closure-switch forms electrical contact in response to a first acceleration and the second cantilevered-beam-closure-switch forms electrical contact in response to a second acceleration, the first acceleration different than the second acceleration;
- wherein the circuit further comprises:
- a memory;
- and
- a timer, wherein the time when one of the first cantilevered-beam-closure-switch forms electrical contact in response to a first acceleration, or the time when the second cantilevered-beam-closure-switch forms electrical contact in response to a second acceleration is stored in memory.
A system comprising:
- a substrate;
- a thin-film battery positioned on the substrate, the thin-film battery further including:
- a first lead;
- a first electrical contact in electrical communication with the first lead;
- a second lead;
- a second electrical contact in electrical communication with the second lead;
- and
- an activity-activated switch connected to one of the first and second lead on the substrate for electrically connecting the thin-film battery to the first electrical contact and the second electrical contact;
- further comprising an adhesive attached to the substrate.
A system comprising:
- a substrate;
- a circuit connected to the substrate;
- a thin-film battery connected to the substrate and connected to the circuit, the thin-film battery adapted to power the circuit;
- and
- a first activity-activated switch connected to the substrate adapted to electrically activate the circuit;
- wherein the circuit further comprises:
- a timer that outputs a timer value based on a time of activation of the first activity-activated switch in response to a first activity.
A method comprising:
- activating an activity-activated switch to place a thin-film battery in communication with a set of electronics;
- storing a start time for a warranty using the powered electronics.
The method comprising:
- adhesively attaching the activity-activated switch, the thin-film battery, and the set of electronics to a product.
