Abstract

A flexible electronic system includes a flexible electronic substrate having a first and second contact pads opposed to each other, one of the first and second contact pads is electrically coupled to a battery. A protective cover is disposed on the flexible electronic substrate. The flexible electronic system further includes a base support fixedly attached to the flexible electronic substrate, the base support having an adhesive surface opposed to the flexible electronic substrate, and a foil having a first portion removably coupled to at least a portion of the adhesive surface and a second portion, wherein the foil configures to permit a removal of the second portion disposed between the first and second contact pads and wherein the removal of the second portion activates the system.

First claim

The invention claimed is:

1. A flexible electronic system comprising:
a battery;
a flexible electronic substrate including a first contact pad and a second contact pad, the first and second contact pads opposed to each other, and one of the first and second contact pads electrically coupled to the battery;
a base support fixedly attached to the flexible electronic substrate, the base support including an adhesive surface opposed to the flexible electronic substrate; and
a foil including a first portion removably coupled to at least a portion of the adhesive surface, and a second portion removably disposed between the first and second contact pads;
wherein removal of the second portion from between the first and second contact pads causes the battery to activate.

2. The flexible electronic system of claim 1 , wherein:
the first portion of the foil is removably attached to a first portion of the adhesive surface;
the foil further includes a third portion removably attached to a second portion of the adhesive surface; and
an end of the third portion is connected to an end of the second portion so as to form a common end for the second and third portions.

3. The flexible electronic system of claim 2 , wherein the first portion includes an end opposed to the end connected to the end of the third portion.

4. The flexible electronic system of claim 2 , wherein the foil further includes a slit between the first portion and the third portion.

5. The flexible electronic system of claim 1 , further comprising a protective cover disposed on the flexible electronic substrate.

6. The flexible electronic system of claim 1 , further comprising a component electrically connected to one of the first and second contact pads.

7. The flexible electronic system of claim 6 , wherein the component is selected from a group consisting of a sensor, a processer, a computer readable media, a communication interface, an ASIC, a capacitor, a transistor, and a resistor.

8. The flexible electronic system of claim 7 , wherein the component and the battery are integrated into the flexible electronic substrate.

9. The flexible electronic system of claim 8 , wherein the flexible electronic substrate is formed from dielectric material.

10. The flexible electronic system of claim 9 , wherein the dielectric material is selected from a group consisting of fiberglass-filled epoxy and polyimide, FR-2 (phenolic cotton paper), FR-3 (cotton payer and epoxy), FR-4 (woven glass and epoxy), FR-5 (woven glass and epoxy), FR-6 (matte glass and polyester), G-10 (woven glass and epoxy), CEM-1 (cotton payer and epoxy), CEM-2 (woven paper and epoxy), CEM-3 (woven glass and epoxy), CEM-4 (woven glass and epoxy), CEM-5 (woven glass and polyester), polystyrene, polyimide, polytetrafluoroethylene (PTFE), plastic, ceramics, and polymer coated with Parylene.

11. The flexible electronic system of claim 10 , wherein:
the flexible electronic substrate further includes a first layer and a second layer;
the component is integrated into the first layer; and
the battery is integrated into the second layer.

12. A flexible electronic system, comprising:
a battery;
a flexible electronic substrate including a first contact pad and a second contact pad, the first and second contact pads opposed to each other, and one of the first and second contact pads electrically coupled to the battery;
a base support fixedly attached to the flexible electronic substrate, the base support including an adhesive surface opposed to the flexible electronic substrate; and
a foil including a first portion removably coupled to at least a portion of the adhesive surface, and a second portion removably disposed between the first and second contact pads,
wherein removal of the second portion from between the first and second contact pads causes the battery to activate, and
wherein the foil further includes a grip portion located between the first portion and the second portion.

13. The flexible electronic system of claim 12 , wherein the grip portion is wrapped around a portion of the system.

14. The flexible electronic system of claim 12 , wherein the grip portion is spaced apart from the base support, so as to define a gap.

15. The flexible electronic system of claim 12 , wherein the grip portion has a slit that is configured to break in order to separate the first portion from the second portion.

16. A flexible electronic system comprising:
a battery;
a flexible electronic substrate including a first contact pad and a second contact pad that are opposed to each other, one of the first and second contact pads electrically coupled to the battery; and
a foil including a first portion and a second portion removably disposed between the first and second contact pads;
wherein removal of the second portion from between the first and second contact pads causes the battery to activate, and
wherein the foil further includes a grip portion located between the first portion and the second portion.

17. The flexible electronic system of claim 16 , wherein the flexible electronic substrate is formed from dielectric material.

18. The flexible electronic system of claim 17 , wherein the dielectric material is selected from a group consisting of fiberglass-filled epoxy and polyimide, FR-2 (phenolic cotton paper), FR-3 (cotton payer and epoxy), FR-4 (woven glass and epoxy), FR-5 (woven glass and epoxy), FR-6 (matte glass and polyester), G-10 (woven glass and epoxy), CEM-1 (cotton payer and epoxy), CEM-2 (woven paper and epoxy), CEM-3 (woven glass and epoxy), CEM-4 (woven glass and epoxy), CEM-5 (woven glass and polyester), polystyrene, polyimide, polytetrafluoroethylene (PTFE), plastic, ceramics, and polymer coated with Parylene.

19. The flexible electronic system of claim 18 , wherein the flexible electronic substrate further includes a first layer and a second layer.

20. The flexible electronic system of claim 19 , further comprising a component electrically connected to one of the first and second contact pads;
wherein the component is integrated into the first layer, and the battery is integrated into the second layer.
