An international team of researchers (Spain, Saudi Arabia, USA – University of Nevada) developed inexpensive benchtop plotters in combination with refillable writing pens and markers as a powerful route to print nanomaterial-based inks on paper substrates using inks of many different solution-processable nanomaterials. It is a robust, precise plotter and allowed printing pattern features with pitch separation as narrow as 80 μm. They illustrated printing van der Waals materials, organic semiconductors, hybrid perovskites and colloidal nanoparticles with a broad range of properties. The system was used to create several example applications such as an all-printed, paper-supported photodetector. According to the researchers their technique allows for the use of virtually any solution-processable nanomaterial ink without the need for expensive equipment or ink optimization, making printed electronics more accessible to researchers… read more.
