Integrated Papertronics for a Sustainable Future

The escalating issue of electronic waste, exacerbated by frequent updates in consumer technology, presents a critical environmental challenge. Conventional electronics, particularly disposable devices, are often not sustainable. Paper-based alternatives, with their favorable mechanical and dielectric properties, offer a sustainable solution. Prior attempts at integrating paper with standard electronic components have fallen short in terms of recyclability and practical deployment. This study introduces an innovative approach for fabricating fundamental electronic components—resistors, capacitors, and transistors— directly onto paper substrates. Employing techniques such as hydrophobic wax patterning, precision ink deposition, and screen-printing, we have successfully created versatile, fully paper-based electronic components. This breakthrough facilitates the development of wholly paper-integrated circuits, representing a leap forward in environmentally sustainable electronics.
