Abstract
The demand for flexible printed electronics is growing fast, especially with the move toward the Internet of Things. These printed electrons are usually designed for short-term use, after which they are disposed of. The polymeric substrates used in printed electronics comprise the biggest portion of their non-biodegradable E-waste after their disposal. This paper demonstrates the feasibility of printing fully functional transient electronics on flexible, water-soluble, and biodegradable paper substrates using the dry printing approach. The in-situ generation and real-time sintering of silver nanoparticles at room temperature enables the fabrication of complex circuits on such water-soluble papers. A layout similar to an Arduino pro mini board is printed on both sides of a paper substrate with electrical interconnects. Various electrical components are then directly mounted to fabricate a complete, working paper Arduino circuit. Cyclic bending tests demonstrate the mechanical durability and reliability of printed paper circuits under repeated bending stress. The process uniquely achieves robust and complex printed electronics without thermal damage, and the water solubility tests successfully show rapid dissolution of the paper devices in water. Furthermore, the components detached during dissolution are collected and reused, demonstrating the recyclability of the process. Overall, this transformative manufacturing method establishes key technical capabilities to produce next-generation sustainable, green electronics and sensors using renewable materials.
期刊介绍:
Flexible and Printed Electronics is a multidisciplinary journal publishing cutting edge research articles on electronics that can be either flexible, plastic, stretchable, conformable or printed. Research related to electronic materials, manufacturing techniques, components or systems which meets any one (or more) of the above criteria is suitable for publication in the journal. Subjects included in the journal range from flexible materials and printing techniques, design or modelling of electrical systems and components, advanced fabrication methods and bioelectronics, to the properties of devices and end user applications.
