Printed electronic components on universally patterned substrate for integrated printed electronics
View Patent ↗A circuit can include a pre-patterned substrate having a supporting material, multiple segments thereon, and interdigitated line structures within each segment. Some of the line structures can be bundled together, and an electrical component can be formed by ink jetting onto the bundled line structures.
1. A circuit, comprising:
a pre-patterned substrate, the pre-patterned substrate including:
a supporting material;
a plurality of segments in direct contact with a surface of the supporting material; and
a plurality of interdigitated parallel, coplanar lines within each segment, wherein some of the interdigitated parallel, coplanar lines are bundled together; and
at least one electrical component formed by ink jetting onto the bundled parallel, coplanar lines.
2. The circuit of claim 1 , wherein the pre-patterned substrate further includes an isolation region between the segments.
3. The circuit of claim 1 , wherein the at least one electrical component includes a resistor, a capacitor, an inductor, or a memristor.
4. The circuit of claim 1 , wherein the at least one electrical component includes a thin film transistor (TFT).
5. The circuit of claim 1 , wherein the jetted ink is carbon ink.
6. The circuit of claim 1 , wherein the bundled parallel, coplanar lines are bundled together by conductive ink jetted onto the interdigitated parallel, coplanar lines.
7. A method, comprising:
providing a substrate;
forming interdigitated coplanar, parallel lines in segments in direct contact with a surface of the substrate;
bundling at least some of the parallel, coplanar lines together; and
forming at least one electrical component by jetting ink onto the bundled parallel, coplanar lines.
8. The method of claim 7 , further comprising defining isolation regions between the segments in which no interdigitated parallel, coplanar lines exist.
9. The method of claim 7 , wherein the at least one electrical component includes a resistor, a capacitor, an inductor, or a memristor.
10. The method of claim 7 , wherein the at least one electrical component includes a thin film transistor (TFT).
11. The method of claim 7 , wherein forming the at least one electrical component includes jetting carbon ink onto the bundled parallel, coplanar lines.
12. The method of claim 7 , wherein bundling at least some of the line structures together includes jetting conductive ink onto the parallel, coplanar lines.
