Abstract

Here we report broad range, tunable and foldable paper-based passive components and filter circuits. Reported electronics fabricated through solvent-free garage fabrication techniques using inexpensive and off-the-shelf materials like graphite pencils, aluminum foil, copper tape, paper, and such Previously reported paper-based passive electronic circuits are single-valued and lack real-time tunability. Broad range passive components and tunable RC filter circuits fabricated through inexpensive, eco-friendly, and cleanroom-free fabrication techniques like hand drawing of graphite pencils on paper and garage fabrication techniques like cutting-pasting of readily available materials demonstrated expected functionalities with tunable cut-off frequencies. Cut-off frequencies of low and high pass filters are tunned from 15 to 190 kHz by penciling graphite flakes of different graphite content pencils. The paper-based passive electronic circuits showed robust performance against applied stress during bending and folding. To the best of our knowledge, no studies have been reported on tunable paper-based passive electronic circuits. These paper-based electronic components and circuits open pathways for green and foldable power electronics, flexible and foldable printed circuit boards and consumer electronics, touchpads, disposable security systems, soft robotics, and many more.

可调谐和可折叠纸基无源电子元件和滤波器电路

摘要

在这里，我们报告了范围广泛、可调谐和可折叠的纸质无源元件和滤波器电路。使用石墨铅笔、铝箔、铜带、纸等廉价和现成材料通过无溶剂车库制造技术制造的报告电子产品以前报道的纸基无源电子电路是单值的，缺乏实时性可调性。广泛的无源元件和可调谐 RC 滤波器电路通过廉价、环保和无洁净室的制造技术制造，例如在纸上手绘石墨铅笔和车库制造技术（例如切割粘贴现成的材料）展示了具有可调谐切割的预期功能。关闭频率。低通滤波器和高通滤波器的截止频率从 15 kHz 到 190 kHz 之间调谐，这是通过对不同石墨含量铅笔的石墨薄片进行铅笔处理来实现的。纸基无源电子电路在弯曲和折叠过程中对施加的应力表现出强大的性能。据我们所知，还没有关于可调谐纸基无源电子电路的研究报告。这些纸质电子元件和电路为绿色和可折叠电力电子、柔性和可折叠印刷电路板和消费电子、触摸板、一次性安全系统、软机器人等开辟了道路。没有关于可调谐纸基无源电子电路的研究报告。这些纸质电子元件和电路为绿色和可折叠电力电子、柔性和可折叠印刷电路板和消费电子、触摸板、一次性安全系统、软机器人等开辟了道路。没有关于可调谐纸基无源电子电路的研究报告。这些纸质电子元件和电路为绿色和可折叠电力电子、柔性和可折叠印刷电路板和消费电子、触摸板、一次性安全系统、软机器人等开辟了道路。
