Abstract
A composite substrate is disclosed. In one aspect, the substrate has a stretchable and/or flexible material. The substrate may further have patterned features embedded in the stretchable and/or flexible material. The patterned features have one or more patterned conducting layers.
Claims20
A stretchable composite substrate, comprising:
- a stretchable material;
- patterned features embedded in the stretchable material, the patterned features comprising one or more patterned conducting layers;
- a plurality of components embedded in the stretchable material and being in electrical or optical contact with the patterned features;
- and
- a local stiffener protecting the components against excess mechanical stress during stretching.

A stretchable composite substrate, comprising:
- a stretchable material;
- patterned features embedded in the stretchable material, the patterned features comprising one or more patterned conducting layers;
- a plurality of components embedded in the stretchable material and being in electrical or optical contact with the patterned features;
- and
- an underfill adhesive material in substantially the whole area confined by the patterned features and the components.

A stretchable composite substrate, comprising:
- a stretchable material;
- patterned features embedded in the stretchable material, the patterned features comprising one or more patterned conducting layers;
- a plurality of components embedded in the stretchable material and being in electrical or optical contact with the patterned features;
- and
- a second set of components in electrical or optical contact with the patterned features, wherein the second set of components are located at the side where the patterned features are free of the stretchable material.
