Printed Electronics Applications: Conductive Tracks and Patterns, Printed Circuits, Functional Electrodes and Flexible Heaters

Printed tracks/patterns with low conductivity are one of the challenges for printed electronics application because they exist in almost every electrical device. All printing methods are applied to manufacture conductive tracks, even high-resolution conductive lines and patterns. These printed tracks can be further given new functions, such as stretchability and self-healing properties, and can also be directly applied to circuits, antennas and flexible heaters. In this chapter, the application of conductive tracks, electrical circuits, electrodes and conductive patterns are demonstrated. Printing methods are also used to fabricate stretchable conductors, self-healing conductors and flexible heaters, exhibiting good electrical properties.
