Humanity's excessive production of material waste poses a critical environmental threat, and the problem is only escalating, especially in the past few decades with the rapid development of powerful electronic tools and persistent consumer desire to upgrade to the newest available technology. The poor disposability of electronics is especially an issue for the newly arising field of single-use devices and sensors, which are often used to evaluate human health and monitor environmental conditions, and for other novel applications. Though impressive in terms of function and convenience, usage of conventional electronic components in these applications would inflict an immense surge in waste and result in higher costs. This work's primary objective is to develop a cost-effective, eco-friendly, all-paper, device for single-use applications that can be easily and safely disposed of through incineration or biodegradation. All electronic components are paper-based and integrated on paper-based printed circuit boards (PCBs), innovatively providing a realistic and practical solution for green electronic platforms. In particular, a methodology is discussed for simultaneously achieving very tunable resistors (20 Ω to 285 kΩ), supercapacitors (∼3.29 mF), and electrolyte-gated field-effect transistors on and within the thickness of a single sheet of paper. Each electronic component is completely integrated into functionalized paper regions and exhibits favorable electrical activity, adjustability, flexibility, and disposability. A simple amplifier circuit is successfully demonstrated within a small area and within the thickness of a single sheet of paper, displaying component versatility and the capability for their fabrication processes to be performed in parallel for efficient and rapid development.
人类过度产生的物质垃圾对环境构成了严重威胁，而且这个问题还在不断升级，尤其是在过去几十年里，随着强大电子工具的迅速发展以及消费者持续渴望升级到最新可用技术。电子产品的难处理性对于一次性设备和传感器这一新兴领域尤其成问题，这些设备和传感器常用于评估人类健康和监测环境状况，以及用于其他新颖应用。尽管在功能和便利性方面令人印象深刻，但在这些应用中使用传统电子元件会导致垃圾大量激增，并带来更高成本。这项工作的主要目标是开发一种具有成本效益、环保的全纸质一次性应用设备，该设备可通过焚烧或生物降解轻松、安全地处理。所有电子元件均基于纸张，并集成在纸质印刷电路板（PCB）上，创新性地为绿色电子平台提供了切实可行的解决方案。特别是，本文讨论了一种方法，可在单张纸的厚度范围内同时实现可调范围很大的电阻器（20Ω至285kΩ）、超级电容器（约3.29mF）以及电解质门控场效应晶体管。每个电子元件都完全集成到功能化的纸区域中，并展现出良好的电活性、可调性、柔韧性和可处理性。一个简单的放大器电路在单张纸的小面积和厚度范围内成功得到演示，展示了元件的多功能性以及它们的制造工艺能够并行进行以实现高效快速开发的能力。
