Extremely stretchable electronics
First Claim
1. A stretchable electrical interconnect, comprising:
- an electrical interconnect for connecting two electrical contacts, said electrical interconnect arranged boustrophedonicially to define rungs between said contacts, said rungs being substantially parallel with one another, and a plurality of said rungs having substantially the same length and displacement therebetween,wherein the ratio of said length of said plurality of said rungs and said displacement between said plurality of said rungs is at least 10;
1; and
wherein the electrical interconnect is made from a semiconductor material.

Abstract
In embodiments, the present invention may attach at least two isolated electronic components to an elastomeric substrate, and arrange an electrical interconnection between the components in a boustrophedonic pattern interconnecting the two isolated electronic components with the electrical interconnection. The elastomeric substrate may then be stretched such that the components separate relative to one another, where the electrical interconnection maintains substantially identical electrical performance characteristics during stretching, and where the stretching may extend the separation distance between the electrical components to many times that of the unstretched distance.
