Conductive ink is a universal way to print electronic circuits on any normally unusable surfaces thanks to their flexible properties. However, these inks have long been costly and inaccessible. However, scientists from ACS Applied Electronic Materials have recently announced their findings on a new, inexpensive type of conductive inks that can be used on nearly any surface.
This water-based ink is created with carbon particles composed of graphene nanosheets, as well as carbon nanotubes and carbon black. Maleic anhydride modified rosin resin is used as a binder, and xanthan gum is used to stabilize the carbon.
The applications these inks have are many in numbers, including being used in conjunction with biosensors and energy storage, as well as being used with electronic skin. Their method of application is also helpful in comparison to their printing counterpart, as they are applied by ballpoint pens, allowing for more deliberate and precise placement on normally unideal surfaces.
