项目摘要

Paper-based electronics and sensors (i.e., Papertronics) are emerging technologies providing a new platform for a wide range of applications for healthcare, environment monitoring, display, and energy storage. Paper as a substrate for next-generation electronics holds significant potential because of its physical and chemical characteristics, including a high surface area to volume ratio, porous structure, biocompatibility, biodegradability, low-cost worldwide availability, foldability, and lightweight. However, the mechanical properties limit intimate integration and conformal contact with living organ systems because the paper is easy to tear and not stretchable. To advance papertronics into bio-integrated soft bioelectronics, paper’s mechanical properties will be modified to make it stretchable while keeping the fibrous structure with bioinert chemical properties to take full advantage of paper’s intrinsic characteristics. The stretchable paper, new material and platform, will be the foundations of the next generation of the papertronics and paperfluidics. Indeed, the stretchable paper can transform into a new domain of interdisciplinary studies putting together basic material science research and engineering sciences to establish groundbreaking innovations. The systematically studied fabrication parameters will accelerate the development of advanced manufacturing, especially in flexible hybrid electronics, and further will be transformed into the production process for use by industry. Knowledge will be disseminated through the development of an educational workshop for STEM teachers, peer-reviewed publications, classroom teaching, student mentoring, and full participation of minorities, women, and underrepresented groups.The proposed project aims to revolutionize paper-based electronics by creating advances in the stretchable co-axial nonwoven fibrous mat using electrospinning technologies. The stretchable papers consist of thin, soft, and core-sheath fibrous platform that will allow becoming elastic but maintaining chemical properties of the paper while using silicone elastomer and cellulose for core material and outer sheath polymer, respectively. Our project involves three objectives to investigate stretchable papertronics. The specific aims are as follows: (1) the thin, nanomesh cellulose coated elastomeric silicone-based polymer substrates will be investigated for mechanically, and biochemically compatible bioelectronics; (2) the stretchable paper will be characterized its physical, chemical, and mechanical properties. The relationship between the fiber diameter and core (or sheath) thickness with processing parameters will be systematically studied. Additionally, the compatibility to the conventional printing technologies will be tested to develop the stretchable paper into functional electronics.; (3) the elastomeric paper-based microbial fuel cell (MFC) will be demonstrated as model papertronics. The 3D cellulose-coated PDMS nanofibers will serve as a substrate for MFC, which generates power for soft bioelectronics with conformal contact with the organ system. Overall, the study of the paper-based electronics validated with the stretchable paper will offer a comprehensive understanding of future developments in the biomechanically compatible papertronics and paperfluidics for inflammatory-free, long-term biomedical applications as well as the environment- and cost-friendly solutions in manufacturing and disposal engineering.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

纸基电子器件和传感器（即，纸电子）是新兴技术，为医疗保健、环境监测、显示和能源存储等广泛应用提供了新平台。纸作为下一代电子产品的基材具有巨大的潜力，因为其物理和化学特性，包括高表面积与体积比、多孔结构、生物相容性、生物降解性、低成本全球可用性、可折叠性和轻质。然而，机械性能限制了与活体器官系统的紧密结合和共形接触，因为纸容易撕裂且不可拉伸。为了将纸电子学推进到生物集成的软生物电子学，将修改纸的机械性能，使其具有可拉伸性，同时保持具有生物惰性化学特性的纤维结构，以充分利用纸的固有特性。可拉伸纸作为一种新的材料和平台，将成为下一代纸电子学和纸流体学的基础。事实上，可拉伸纸可以转变为跨学科研究的新领域，将基础材料科学研究和工程科学结合起来，以建立突破性的创新。系统研究的制造参数将加速先进制造的发展，特别是在柔性混合电子领域，并将进一步转化为工业生产过程。通过为STEM教师举办教育研讨会、同行评审出版物、课堂教学、学生辅导以及少数民族、妇女和代表性不足的群体的充分参与，传播知识。拟议项目旨在通过利用静电纺丝技术在可拉伸同轴非织造纤维垫方面取得进展，彻底改变纸基电子产品。可拉伸纸由薄的、软的和芯-鞘纤维平台组成，其将允许变得有弹性但保持纸的化学性质，同时分别使用硅酮弹性体和纤维素作为芯材料和外鞘聚合物。我们的项目包括三个目标，研究可拉伸纸电子学。具体目标如下：（1）将研究薄的纳米网纤维素涂覆的弹性硅基聚合物基底的机械和生物化学相容性生物电子学;（2）可拉伸纸将表征其物理，化学和机械性能。系统地研究了纤维直径和芯（鞘）层厚度与工艺参数的关系。此外，还将测试与传统印刷技术的兼容性，以将可拉伸纸开发成功能性电子产品。(3)弹性纸基微生物燃料电池（MFC）将作为模型纸电子学进行演示。3D纤维素涂层的PDMS纳米纤维将作为MFC的基底，MFC为与器官系统共形接触的软生物电子学产生电力。总的来说，使用可拉伸纸验证的纸基电子学的研究将全面了解生物力学兼容的纸电子学和纸流体学的未来发展，长期的生物医学应用以及环境-和成本-该奖项反映了NSF的法定使命，并通过使用基金会的学术价值和更广泛的影响审查标准。
