Stretchable electronic circuit

摘要

A stretchable electronic circuit that includes a stretchable base substrate having a plurality of stretchable conductors formed onto a surface thereof, with both the stretchable base substrate and conductors being bendable together about two orthogonal axes. The stretchable circuit also includes a stretchable sensor layer attached to the base substrate with a cavity formed therein which has a contact point exposing one of the plurality of stretchable conductors. The stretchable electronic circuit further includes a surface mount device (SMD) package with a conductor contact protrusion installed into the cavity, and wherein a substantially constant electrical connection is established between the conductor contact protrusion and the stretchable conductor at the contact point by tensile forces interacting between the stretchable base substrate and the stretchable sensor layer.

1. A stretchable electronic circuit, comprising:
a stretchable base substrate having a plurality of stretchable conductors formed onto a surface thereof; both the base substrate and conductors being bendable together about at least two orthogonal axes; a stretchable sensor layer attached to the base substrate and having a surface mount device (SMD) cavity formed therein, the SMD cavity including at least one contact point exposing at least one of the plurality of stretchable conductors; and an SMD package having a conductor contact protrusion installed into the SMD cavity, wherein tensile forces interacting between the stretchable base substrate and the stretchable sensor layer maintain a substantially constant electrical connection between the conductor contact protrusion and the stretchable conductor at the contact point.
