Abstract:
1. A stretchable electronic circuit, the circuit having a central longitudinal axis and the circuit being stretchable in a longitudinal direction generally aligned with the central longitudinal axis, comprising: a solid stretchable polymer body made entirely of poly(dimethylsiloxane), said solid stretchable polymer body made entirely of poly(dimethylsiloxane) having a polymer body longitudinal axis that is concurrent with the central longitudinal axis of the circuit, at least one microchannel in said solid stretchable polymer body made entirely of poly(dimethylsiloxane), said at least one microchannel having a microchannel longitudinal axis that is concurrent with the central longitudinal axis of the circuit, wherein said at least one microchannel extends fully along said microchannel longitudinal axis, a multiplicity of microchannel longitudinal components that extend in the longitudinal direction, and a multiplicity of micro channel offset components that are at an angle to the longitudinal direction, and an electrically conductive media contained in said at least one microchannel, wherein said at least one microchannel and said electrically conductive media form an electronic circuit line that extends fully along said microchannel longitudinal axis and is operatively connected to said solid stretchable polymer body made entirely of poly(dimethylsiloxane), said at least one electronic circuit line extending in the longitudinal direction and having a multiplicity of circuit line longitudinal components that extend in the longitudinal direction, wherein said multiplicity of circuit line longitudinal components include said multiplicity of microchannel longitudinal components and having a multiplicity of circuit line offset components that extend at an angle to the longitudinal direction, wherein said multiplicity of circuit line offset components include said multiplicity of microchannel offset components, said circuit line longitudinal component and said circuit line offset component allowing the circuit to stretch in the longitudinal direction while maintaining the integrity of said at least one circuit line.
