Abstract
A stretchable and transparent electronic structure may generally include a stretchable elastomer layer; optionally, a metal adhesion layer on top of the stretchable elastomer layer; a metal alloying layer on top of the metal adhesion layer; and a liquid metal, wherein the structure is colorless and transparent when viewed under visible light. Methods of making the stretchable and transparent electronic structure are also described.
Claims20
A stretchable and transparent electronic structure comprising:
- a stretchable elastomer layer;
- a metal alloying layer on top of the stretchable elastomer layer;
- and
- a liquid metal,
- wherein the structure is colorless and transparent when viewed under visible light.
A method of manufacturing a stretchable and transparent electronic structure, the method comprising laser patterning an electrically conductive material layer on a stretchable substrate to form a plurality of void spaces therein, wherein the electrically conductive material layer comprises biphasic metallic grid lines having a thickness up to 600 nanometers and a width up to 6 micrometers, wherein the structure comprises, based on the structure's total top surface area, up to 15% of the electrically conductive material layer and at least 85% void spaces, and wherein the structure is colorless and transparent when viewed under visible light.
