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.

干式印刷全功能环保型一次性瞬态纸张电子元件
对柔性印刷电子产品的需求正在快速增长,特别是随着物联网的发展。这些印刷电子产品通常是为短期使用而设计的,之后就会被丢弃。印刷电子产品中使用的聚合物基底在废弃后的不可生物降解电子垃圾中占最大比例。本文展示了利用干式印刷方法在柔性、水溶性和可生物降解的纸质基底上印刷全功能瞬态电子器件的可行性。银纳米粒子在室温下的原位生成和实时烧结使得在这种水溶性纸张上制造复杂电路成为可能。类似于 Arduino pro 迷你电路板的布局被印刷在纸基板的两面,并带有电气互连。然后直接安装各种电气元件,制作出一个完整的、可工作的纸质 Arduino 电路。循环弯曲测试证明了印刷纸电路在反复弯曲应力下的机械耐久性和可靠性。该工艺独特地实现了坚固而复杂的印刷电子元件,且不会产生热损伤,水溶性测试成功显示了纸器件在水中的快速溶解。此外,溶解过程中脱落的元件可以收集起来重新使用,这证明了该工艺的可回收性。总之,这种变革性的制造方法建立了利用可再生材料生产下一代可持续绿色电子器件和传感器的关键技术能力。

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.
