The new textile electronic devices are based on low-cost, sustainable and scalable inkjet printing of inks based on graphene and other two-dimensional materials, and are produced by standard processing techniques.
In earlier days, the formulation of graphene inks for printed electronics were low-boiling point inks, which were directly printed onto polyester fabric. Additionally, modifying the roughness of the fabric improved the performance of the printed devices. The versatility of this process allowed the researchers to design not only single transistors but all-printed integrated electronic circuits combining active and passive components.
Most wearable electronic devices that are currently available rely on rigid electronic components mounted on plastic, rubber or textiles. These offer limited compatibility with the skin in many circumstances, are damaged when washed and are uncomfortable to wear because they are not breathable.
This is the first digital textile printing which can be used to print Electronic IC on textile. This process is scalable and no fundamental obstacles. The printed components are flexible, washable and require low power, essential requirements for applications in wearable electronics.
