Abstract

A stretchable electronic assembly comprising a stretchable body, a plurality of electronic components encapsulated in the stretchable body, at least one meandering conductor connected to at least one electronic component of the plurality of electronic components, at least one hollow pocket formed in the stretchable body, the at least one meandering conductor encapsulated in the stretchable body and the at least one meandering conductor located within the at least one hollow pocket formed in the stretchable body.

First claim

What is claimed is:

1. A stretchable electronic assembly, comprising:
a stretchable body;
a plurality of electronic components encapsulated in the stretchable body;
at least one non-meandering hollow pocket formed in the stretchable body; and
one or more meandering conductors connected to one or more electronic components of the plurality of electronic components via one or more end portions of the one or more meandering conductors, wherein at least each of the one or more meandering conductors aside from the one or more end portions is encapsulated within the at least one non-meandering hollow pocket.

2. The stretchable electronic assembly of claim 1 , wherein:
at least one of the one or more meandering conductors located within the at least one non-meandering hollow pocket has a length; and
at least a portion of the length of the at least one meandering conductor located within the at least one non-meandering hollow pocket is unsecured in the at least one non-meandering hollow pocket.

3. The stretchable electronic assembly of claim 1 , wherein:
at least one of the one or more meandering conductors located within the at least one non-meandering hollow pocket has a length; and
at least a portion of the length of the at least one meandering conductor located within the at least one non-meandering hollow pocket is unsecured from the stretchable body.

4. The stretchable electronic assembly of claim 1 , wherein:
the at least one non-meandering hollow pocket is larger than the one or more meandering conductors, such that at least a portion of the one or more meandering conductors located within the at least one non-meandering hollow pocket is spaced from the stretchable body by the hollow pocket.

5. The stretchable electronic assembly of claim 1 , wherein a meandering additional hollow pocket is formed in the stretchable body, wherein the stretchable electronic assembly comprises multiple meandering conductors connected to the one or more electronic components of the plurality of electronic components, and wherein one of the multiple meandering conductors is located within the meandering additional hollow pocket.

6. The stretchable electronic assembly of claim 1 , wherein:
at least one of the one or more meandering conductors encapsulated within the at least one non-meandering hollow pocket comprises a substantially sinusoidal path.

7. The stretchable electronic assembly of claim 1 , wherein:
the one or more meandering conductors comprises a plurality of meandering conductors each connected to at least one electronic component of the plurality of electronic components;
each of the plurality of meandering conductors are encapsulated in the stretchable body; and
each of the plurality of meandering conductors are located within a same non-meandering hollow pocket of the at least one non-meandering hollow pocket formed in the stretchable body.

8. The stretchable electronic assembly of claim 1 , wherein:
the one or more meandering conductors comprises a plurality of meandering conductors each connected to at least one electronic component of the plurality of electronic components;
the at least one non-meandering hollow pocket formed in the stretchable body comprises a plurality of non-meandering hollow pockets formed in the stretchable body;
each of the plurality of meandering conductors are encapsulated in the stretchable body; and
each of the plurality of meandering conductors are located within a different non-meandering hollow pocket of the plurality of non-meandering hollow pockets formed in the stretchable body.

9. The stretchable electronic assembly of claim 1 , wherein:
the at least one meandering conductor connected to at least one electronic component of the plurality of electronic components comprises an electrical trace.

10. The stretchable electronic assembly of claim 9 , wherein:
the at least one meandering conductor connected to at least one electronic component of the plurality of electronic components further comprises an electrical insulator which overlies the electrical trace.

11. The stretchable electronic assembly of claim 10 , wherein:
the electrical insulator is a dielectric insulator.

12. The stretchable electronic assembly of claim 1 , wherein:
the stretchable body is formed of a thermoplastic or thermoset polymer.

13. The stretchable electronic assembly of claim 1 , wherein:
the stretchable body is formed of an elastomer.

14. The stretchable electronic assembly of claim 1 , wherein:
the stretchable body comprises at least one molded body.

15. The stretchable electronic assembly of claim 1 , wherein:
the stretchable body comprises a film.

16. The stretchable electronic assembly of claim 1 , wherein:
the at least one meandering conductor provides an antenna.
